    摘要: A multi-channel spectral imaging module for an automated testing system for cytological applications. The multi-channel spetral imaging module generates four channels of digitized images of a cytological specimen for further processing in the automated testing system. The multi-spectral imaging module comprises a visible light source and an infrared light source, an optical imaging module, a prism module, and an output stage. The cytological specimen is strobed by the visible light and infrared light sources and the illuminated images of the specimen are focussed and coupled to the prism module by the optical imaging module. The prism module breaks the illuminated image into four channels comprising three visible light channels and an infrared channel. The output stage comprises a CCD array sensor for each channel. The CCD array sensor digitizes the image for channel and produces an output for further processing. The digitized output from the infrared channel provides additional information which is used by the automated testing system. The additional information derived from the infrared channel includes segmentation information, new identifying features for the specimen, and discrimination measures independent of the visible light channels. In another embodiment, a fifth channel is provided for a reference infrared output and the two infrared channels are operated in a differential mode.
