Method and device for determining the phase- and/or amplitude data of an electromagnetic wave

The invention involves a phase and/or amplitude data for determining electromagnetic method and corresponding device. To makes used such a method obtained of figure like data has space depth resolution, according to this invention of method contains following steps: make electromagnetic waves into beam in at least contains a pixel of light mixed components of surface Shang, the pixel at least has two a photosensitive modulation light door Gam and Gbm and related of accumulated door Ga and Gb; will modulation light door voltage Uam and Ubm imposed to modulation light door Ga and Gb Shang, and modulation light door voltage of constitute is Uam (t) =Uo+Um (t), Ubm (t ) =Uo-Um (t); will DC voltage imposed to accumulated door Ga and Gb Shang, and DC voltage of range at least and Uo and modulation voltage Uam (t) of range of sum same; make by incident electromagnetic waves in modulation light door Gam and Gbm of space charge district in the produced of carrier suffered drift field of potential gradient, and drift to corresponding of accumulated door Ga or Gb, and electromagnetic waves is modulation light door voltage Uam (t) and Ubm (t) of polar of function; Have separately drift to accumulate of Ga and Gb charge reversed. Mixing elements of at least one pixel, the pixel contains at least two photo-sensitive modulated light (Gam,Gbm) and the two modulated light-related and cumulative separated to the incident electromagnetic wave (Ga,Gb). Can consist of multiple optical mixing elements are grouped together into a single array.
