Abstract

A method and apparatus of a plurality of detecting elements for detecting and producing an image of an object includes a signal generator for generating a waveform signal, a laser for producing a light signal modulated by the waveform signal, and a mixing and detecting device coupled to and driven by the signal generator for converting reflected light signals received from the target into electrical signals and for mixing the converted electrical signals with the waveform signal to produce an output electrical signal. A read-out is connected to the mixing and detecting device for removing the output electrical signals from the mixing and detecting, and a signal processor is connected to the read-out for processing the output electrical signals from the read-out to detect and produce and image of the object.
