FIELD: photodetectors. ^ SUBSTANCE: proposed photodetector has transparent substrate with two interference-sensing photoelectric cells and electrodes. Difference in optical distances from plane perpendicular to light beam being measured that confines photoelectric cell and from second photoelectric cell to this plane Deltalopt = klambda/4, where lambda is wavelength of photodetector spectral sensitivity extreme; k is positive integer number. ^ EFFECT: ability of generating in-phase and antiphase signals for opposing light fluxes selective with respect to interference-field measurement wavelength. ^ 1 cl, 4 dwg |
