Abstract

Procedure with your device to detect halograms of an object, characterized by: - transmit a signal to said object, to produce a reflected signal from the objects - supply a reference signal that has a frequency identity with the transmitted signal - deriving a holographic signal having continuous amplitude values, formed by the reflected signal by superimposing it on the reference signal; and - transforming said holographic signal into an electrical output signal having only two discrete amplitude values.
