METHOD AND DEVICE DETERMINING INFORMATION ON AMPLITUDE AND PHASE OF ELECTROMAGNETIC WAVE Russian patent published in 2002 - IPC

FIELD: study of electromagnetic waves. SUBSTANCE: method in compliance with invention has several stages to achieve spatial resolution of data of image in depth. Electromagnetic wave is directed on to surface of element of photon shift containing one pixel as minimum. Pixel incorporates at least two light-sensitive modulation light valves G_am and G_bm and coupled reservoir valves G_a and G_b. Voltages U_am(t) and U_bm(t) of modulation of light valves which have configuration in the form of U_am(t) = U₀+U_m(t) and U_bm(t) = U₀,- U_m(t) are applied to modulation light valves U_am and U_bam. Forward voltage whose value is at least equal to value of total voltage U₀ and amplitude of modulation voltage U_m(t) is applied to reservoir valves G_a and G_b. Charge carriers obtained in region of spatial charge of modulation light valves G_am and G_bm are subjected to effect of gradient of potential field of drift and drift in corresponding reservoir valve G_a or G_b with the aid of incident electromagnetic wave in the form of function of polarity of voltages U_am(t) and U_bm(t). Then charges q_a and q_b which drifted to reservoir valve G_a and G_b correspondingly are removed. Proper element of photon mixing has at least one pixel containing light-sensitive modulation light valves (G_am, G_bm) and reservoir valves (G_a, G_b). They are coupled to modulation light valves and are divided into parts relative to incident electromagnetic wave. Assemblage of elements of photon shift can be grouped to form block. EFFECT: increased efficiency of process of determination of information on phase and amplitude of electromagnetic wave. 33 cl, 14 dwg
