IPC: G06T1/00
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To measure the shape of an uneven pattern by a method wherein illumination light is irradiated from an oblique part in a region to be measured, reflected light is formed as an image by an object-side or image-side telecentric optical system in which an object-sides angular aperture with reference to one point in the region is set at a prescribed angle, the image is imaged, luminance data on every point is acquired so as to be frequency-decomposed and a prescribed frequency component is extracted and synthesized. SOLUTION: A point light source is formed of a point light source 111 and of an aperture diaphragm 112, and an object-side angular aperture is set in such a way that reflected light on a face parallel to a plane at right angles to an incident direction is wholly incident on an opening in an aperture diaphragm 310 at an angular-aperture variable mans 330. The reflected light is formed as an image at a luminance according to an angle of incidence in every point in the region, to be measured, by illumination light by using an object-side telecentric optical system 300, and the image is imaged by an imaging part 400. Luminance data on every pixel is acquired by a procession part 510.  The processing part 510 instructs a data conversion part 520 about a prescribed direction, and frequency data on a high-frequency component is inverse-Fourier-transformed by the conversion part so as to be sent to the processing part 510. A frequency component is extracted from the image which is imaged by the imaging part 400, and an uneven pattern is obtained.

Title: Signal transmission system
Inventor: SASAI TOSHIHIKO
IPC: H04L12/40
Filed: 1989-03-31
Abstract: PURPOSE:To relieve the load for a transmission signal sending processing of a central processing unit and to make the synchronization with other equipment easy by selecting one frame of transmission to be a prescribed time width, keeping a voltage on a transmission line at a prescribed state after the transmission of one frame data, and awaiting the succeeding frame. CONSTITUTION:A central processing unit 1 executes the transmission processing for each prescribed time by timer interrupt or the like and keeps a line voltage of a transmission line 3 constant to await the start of a succeeding frame when the transmission of one frame data is finished from the end of return from terminal equipments 5-1, 5-2... since the voltage mode of the transmission line is kept constant for the transmission processing during the standby period and the start of the succeeding frame such as timer interrupt is awaited, the desired processing is executed. Moreover, even when a transmission bit number is changed, the change in the transmission time is absorbed by expanding or contracting the standby time and the length of the frame is unchanged. Thus, the synchronization with the other equipment is easily taken.
