Abstract

See full text

A contact image sensor includes a preset scanning plane used for the surface to be scanned to map to the original copy. The contact image sensor includes: a timing circuit: for self-generating light source control signal LRDT and line scan control signal TRIG1; a lens: for collecting reflected light emitted by a light source reflected by the original copy and emitting the reflected light onto a photoelectric conversion chip for converting received optical signals into electrical signals; and a data processing unit: emitting trigger pulse TRIG according to the encoder transmitting the object to be detected, receiving and processing electrical signals output by the photoelectric conversion chip that has the same size of the photoelectric signal output, ensuring the output stability, dynamic range and sensitivity of the image sensor.
