| abstract | PURPOSE: To eliminate dispersion in received light, by providing a PLZT electronic chopper having the functions of optical modulation and a filter in a light projecting system, changing a voltage applied to the chopper, thereby changing spectroscopic transmittance. n CONSTITUTION: A light projecting system 20 is formed by a light source lamp 1, a light projecting optical system 3 and a PLZT electronic chopper 14. A polarizing plate 18 is bonded to a PLZT wafer 16 having an electrode 15 by a low- viscosity resin 17. Glass 19 is stuck to each of the polarizing plates 17. Thus the chopper 14 is formed. A light receiving system 21 is formed by a light receiving optical system 8 and a light receiving element 11. A driving circuit 23 for the chopper 14 and an I-V conversion amplifier circuit 22 of the electric signal of the element 11 are controlled by a control circuit 24. A voltage applied to the chopper 14 is changed and its spectroscopic transmittance is changed. The color of the reflected light from a body 2 is judged. Thus movable parts can be omitted from the light projecting and receiving systems 20 and 21. n COPYRIGHT: (C)1986,JPO&Japio |
