OPTOELECTRONIC FUNCTIONAL CONVERTER Russian patent published in 1995 - IPC

FIELD: optoelectronic instrumentation enmgineering. SUBSTANCE: optoelectronic functional converter has light-tight case 1, light source 2, light probe shaping unit 3, inlet axis 4, circula raster photopotentiameter 5 in the form of dielectric substrate 6 carrying resistive layer 7, photoconducting layer 8, comb-sheped collector electrode 9, n+1 flat radial electrodes 10. Light probe shaping unit is defocused to degree satisfying condition 3θ<β-α ≅ 360 -ζ-α ,, where θ is angular length of raster photopotentiometer sections; b and a is angular distance from center of light probe whereon surface illumination of photoconductive layer of photopotentiometer is 10^-3 and 0.5 of maximum illumination, respectively; ζ is effective angle of circular raster photopotentiometer. K additional sections ((1≅K≅α/θ)) are made at end of photopotentiometer similar in structure to main sections of photophotopotentiometer provided with additional electrodes. EFFECT: improved design. 2 dwg
