Title: Scanner opto-mechatronic system with fixed detector and moving mirror

Description:
FIELD OF THE INVENTION 
     The present invention relates to a scanner opto-mechatronic system with fixed detector and moving mirror which is used in the measurement of mages and light coming from certain directions. 
     In particular, the present invention relates to a scanner opto-mechatronic system with fixed detector and moving mirror which performs the measurement or imaging of these regions on a single axis and with a single motor orientation by reducing the light measurement and imaging regions to predefined regions. 
     STATE OF THE ART 
     Today, when taking images from the regions determined or measuring the electromagnetic radiation coming from these regions, a lightmeter or imaging device must be directed to these areas together with an optical system. 
     A typical system used in the measurement of images and light from 3D space can be given as an example of the systems used in the state of the art for image and light measurement from certain directions. This typical system mainly comprises a telescope that provides orientation to the desired region so as to display a region in the sky, and a lightmeter attached to the focal plane connected to a telescope or CCD camera that acts as a displaying unit. Two motors in the telescope move the telescope in two rotation axes, and thus the telescope is directed to the desired area. At the same time, the power and signal cables connected to the camera and telescope also move with the telescope. This system allows the visualization or measurement of nearly the entire region. However, the possibility of technical failure in the system increases due to many components such as motor, motor driver, mechanical driver components, belt and similar motion transmission elements contained in said system. Furthermore, the system may be damaged due to tension, rupture or entanglement in the cables since the camera and signal cables connected to the moving axis of the telescope move with the telescope. This condition is even more important in remotely operated systems and makes it difficult to make the necessary intervention within a short period of time. 
     It may take time for structures with complex systems to be directed to a specific target with the abovementioned system. This reduces the time resolution of the measurement and poses an obstacle for more frequent data acquisition. Difficulties may occur in timely intervention to technical malfunctions in such systems due to transportation difficulties and lack of technical personnel. 
     As a result, abovementioned problems and the insufficiency of the current solutions makes it necessary to make a development in the relevant technical field. 
     SUMMARY OF THE INVENTION 
     The present invention relates to scanner opto-mechatronic system with fixed detector and moving mirror which eliminates the abovementioned disadvantages and brings new advantages to the relevant technical field. 
     The main aim of the invention is to ensure that images from certain special regions fall onto a fixed light measurement/imaging system by means of a series of mirrors positioned in a special position and orientation, and the mechanical structure in the specially designed form on which these mirrors are mounted with only one motor. 
     The aim of the invention is to prevent the damages that occur in the system due to the tension, breakage or entanglement of the cables by ensuring that the signal or power cables are fixed by means of the fixed display. 
     Another aim of the invention is to perform the measurement or imaging of these regions on a single axis and with a single motor orientation, without the need for complex systems, and to ensure that the image of the desired region falls on the photometer/imager device by reducing the light metering and imaging regions to predefined regions. 
     Another aim of the invention is to ensure that the technical problems in the system are reduced to a minimum with the help of a structure with a minimum number of parts. 
     Another aim of the invention is to eliminate the problems experienced in remotely managed conditions where transportation and technical intervention are difficult by minimizing the possibility of technical failure. 
     Another aim of the invention is to enable it to be directed to the target area in a short time and thus to obtain more frequent data with the help of its simple structure and operation with a single axis.

     DETAILED DESCRIPTION OF THE INVENTION 
     In this detailed description, the preferred alternatives of the inventive scanner opto-mechatronic system are described only for clarifying the subject manner such that no limiting effect is created. 
     The general view of the inventive scanner opto-mechatronic system is given in  FIG.  1   . Accordingly, scanner opto-mechantronic system mainly comprises the following; body ( 10 ) which has at least four displaying windows ( 11 ) that carry the light/image (A) coming from the predefined regions to the system and at least one light/image output window ( 12 ) that allows the light/image (A) coming into the scanner opto-mechatronic system to exit from the scanner opto-mechatronic system, at least four mirrors ( 20 ) that move within the body ( 10 ) and positioned in the desired position, reflecting the light/image (A) coming from the pre-defined regions, mirror holder ( 30 ) that connects the mirrors ( 20 ) inside the body ( 10 ) at an angle and brings one of the mirrors ( 20 ) to the desired position by making a rotational movement, motor ( 60 ) that enables the mirror holder ( 30 ) to rotate, foot ( 70 ) that connects the motor ( 60 ) to the body ( 10 ), motor driver electronic module ( 80 ) that provides energy for the motor ( 60 ) to rotate in the desired direction and speed according to the selection of the region to be measured, encoder disc ( 90 ) that determines the amount of movement of the motor ( 60 ), encoder reader ( 100 ) that reads the encoder disk ( 90 ), control system ( 110 ) that controls and commands the operating regime of the scanner opto-mechatronic system according to the commands given for the region to be measured, lightmeter/camera ( 130 ) that measures and displays the light/image (A) reflected from a suitable mirror ( 20 ) positioned in front of the light/image output window ( 12 ). 
     The body ( 10 ) which constitutes the main structure of the inventive scanner opto-mechatronic system is in the form of a rectangle, there are at least four viewing windows ( 11 ) that carry the light/image (A) coming from the predefined regions to the scanner opto-mechatronic system and at least one light/image output window ( 12 ) that allows the light/image (A) coming from the predefined regions to the scanner opto-mechatronic system to exit from the scanner opto-mechatronic system on the body ( 10 ). 
     A mirror holder ( 30 ) that performs rotational movement is located inside the body ( 10 ). As seen in  FIGS.  2  and  3   , at least four mirrors ( 20 ) are attached to the mirror holder ( 30 ) by means of mirror adjusting screws ( 40 ) and strip springs ( 50 ). The mirror adjusting screws ( 40 ) seen in  FIG.  4    pushes the mirrors ( 20 ) by pressing on the springs ( 50 ) connected to the mirror holder ( 30 ) so as to ensure precise positioning of the mirrors ( 20 ) on the mirror holder ( 30 ). In case the mirror adjusting screws ( 40 ) are loosened, the mirrors ( 20 ) move backwards together with the mirror holder screws ( 40 ) by means of the strip spring ( 50 ). 
     Mirror holder ( 30 ) that connects the mirrors ( 20 ) inside the body ( 10 ) at an angle makes a rotational movement within the body ( 10 ) and brings one of the mirrors ( 20 ) to the desired position in front of the light/image output window ( 12 ). Only one of the light/image (A) coming from the displaying windows ( 11 ) is reflected onto the light/image output window ( 12 ) by means of the selected appropriate mirror ( 20 ) angle. The number of mirrors ( 20 ) in the body ( 10 ) and the number of displaying windows ( 11 ) can be increased. 
     As seen in  FIG.  5   , the mirror holder ( 30 ) is moved by the motor ( 60 ) connected to the body ( 10 ) by means of a foot ( 70 ). Motor driver electronic module ( 80 ) is connected to the motor ( 60 ) and provides energy for the motor ( 60 ) to rotate in the desired direction and speed according to the selection of the region to be measured. 
     An encoder disc ( 90 ) is connected to the shaft of the motor ( 60 ) so as to determine the amount of movement of the motor ( 60 ). Said encoder disk ( 90 ) can be selected as magnetic, optical, capacitive, inductive and the like. Said encoder disc ( 90 ) is associated with an encoder reader ( 100 ). The rotation information of the encoder disc ( 90 ) is read by the encoder reader ( 100 ). 
     The operating principle of the scanner opto-mechatronic system is controlled and commanded by the control system ( 110 ) according to the commands given for the region to be measured. 
     Said control system ( 110 ) seen in  FIG.  6    essentially comprises a control system interface panel ( 111 ) that consists of a control panel power input ( 1111 ) and a control panel data input port ( 1112 ) containing USB, wireless and Ethernet type port connections and control card ( 112 ) that is adjacent to the control system interface panel ( 111 ) for the energy supply of the scanner opto-mechatronic system. 
     Selection of the region to be measured, computer, microcontroller, etc. is carried out with the help of the commands sent to the control system ( 110 ) via a module with similar calculation and decision-making capabilities. The energy supply of the scanner opto-mechatronic system is provided with the supply voltage via the control panel supply input ( 1111 ). Control signals are given over the control panel data input port ( 1112 ). 
     Motor driver electronic module ( 80 ) is connected to the control card ( 112 ) by means of a motor driver control data cable ( 120 ). The command for the selected region to be measured is transmitted to the motor driver electronic module ( 80 ) via the motor driver control data cable ( 120 ) via the preferred control panel data input port ( 1112 ) and a suitable mirror ( 20 ) selected is positioned in front of the light/image output window ( 12 ) by the rotation of the mirror holder ( 30 ) providing the movement of the motor ( 60 ). The rotation information of the encoder disk ( 90 ) is continuously read by the encoder reader ( 100 ) so as to stop the mirror holder ( 30 ) as soon as it reaches the appropriate position. In case the information that the mirror holder ( 30 ) is in the desired position is received by the control card ( 112 ), the motor ( 60 ) is stopped by the motor driver electronic module ( 80 ). 
     The lightmeter/camera ( 130 ), which measures and displays the image/light (A) reflected from the selected appropriate mirror ( 20 ) coming from predefined regions (specific coordinates) in three-dimensional environments, is positioned in the light/image output window ( 12 ). 
     The energy supply of the lightmeter/camera ( 130 ) is provided by the power cable ( 140 ) connected to the lightmeter/camera ( 130 ). 
     The data communication between the lightmeter/camera ( 130 ) and the computer is provided via the data cable ( 150 ). 
     The operating principle of the inventive scanner opto-mechatronic system is as follows; 
     The energy supply of the scanner opto-mechatronic system is provided with the supply voltage via the control panel supply input ( 1111 ). 
     Selection of the region to be measured, computer, microcontroller, etc. is carried out with the help of the commands sent to the control system ( 110 ) via a module with similar calculation and decision-making capabilities over preferred control panel data input port ( 1112 ). 
     The command for the selected region to be measured is transmitted to the control card ( 112 ) via the preferred control panel data input port ( 1112 ) and to the motor driver electronic module ( 80 ) via the motor driver control data cable ( 120 ). The motor ( 60 ) is moved and the mirror holder ( 30 ) is rotated by means of the motor driver electronic module ( 80 ). 
     One of the mirrors ( 20 ) is brought to the desired position in front of the light/image output window ( 12 ) and at that time, the encoder disk ( 90 ) rotation information is continuously read by the encoder reader ( 100 ) and transmitted to the control card ( 112 ) so as to stop the mirror holder ( 30 ) as soon as it reaches the appropriate position. In case the information that the mirror holder ( 30 ) is in the desired position is received by the control card ( 112 ), the motor ( 60 ) is stopped by the motor driver electronic module ( 80 ). 
     As seen in  FIG.  7   , the light/image (A) coming from the displaying windows ( 11 ) is reflected to the light/image output window ( 12 ) by means of an appropriate selected mirror ( 20 ) selected which is brought to the desired position in front of the light/image output window ( 12 ) and the reflected light/image (A) is positioned in front of the light/image output window ( 12 ) and the measurement and imaging process is performed by means of a lightmeter/camera ( 130 ) powered by a power cable ( 140 ). The information generated by the measurement and imaging process with the lightmeter/camera ( 130 ) is transmitted to the external environment by means of the data cable ( 150 ).
