Title: Tri-metrogon scanning type distance measuring device and method for measuring distance
Inventor: OTOMO HIROAKI
IPC: G01B11/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To reduce a measuring error of a distance caused by a secondary reflection on an object in scanning a light beam. SOLUTION: A floodlamp 1 scans a light beam in one plane. The light beam scanned is partly branched by means of a beam splitter 15 and a position of the light beam branched is detected by means of a scan sensor 16.

IPC: H04B10/07
Filed: 1978-04-12
Abstract: PURPOSE: To let automatic adjustment of the optimum level to be performed according to the increase or decrease in input photo signal by a simple circuit constitution of converting the photo  signal to electric signal with a photo detector, comparing this with a reference voltage in a comparator and performing level judgement.  
     CONSTITUTION: When light Pin enters a photo detector 1, output current i 1  generates in the  photo detector 1. This causes voltages to be generated at both end (a) point and (b) point of a  resistance R 1 . The voltage at the (b) point becomes steady state by the integrating circuit having  the time constants of a resistance R 2  and capacitor C. This voltage at the (b) point is made the  reference voltage of a comparator 2. The voltage at the (a) point is the voltage at the (b) point  added with the voltage drop component by the resistance R 1 . Here the voltage at the (a) point is  divided by the resistances R 3  and R 4  and the voltage at the point P of connection between the  resistances R 3  and R 4  is made the input to the comparator 2. The voltages at the (a) point and  (b) point are determined by the current generated by the photo detector 1 and therefore even if  the input light changes, it turns out that the discrimination level is set always within the change  range of the input signal.
