ABSTRACT:
A detection system for detecting information using a charge-coupled device comprises a charge-coupled device supplied with a clock pulse having a predetermined frequency and producing an output signal pulse, a memory device for storing a set of orthogonal functions, and a processing unit supplied with the output signal pulse from the charge-coupled device sequentially in response to the clock pulse and further for reading out the orthogonal functions stored in the memory device, wherein the processing unit expands each output signal pulse of the charge-coupled device into an orthogonal series using the orthogonal functions as a base of expansion, and extracts a term in the orthogonal series that corresponds to the signal component representing the information detected by the charge-coupled device as an output signal.
