The invention discloses a weak fluorescence signal acquisition device in an endoscope imaging system. The weak fluorescence signal acquisition device in the endoscope imaging system comprises a CCD, a pre-amplification module, an analog signal processing module, a power driving module, an A / D, a digital signal processor, a data acquisition card and a data caching module. The CCD, the pre-amplification module, the analog signal processing module, the power driving module, the A / D, the digital signal processor, the data acquisition card and the data caching module are sequentially connected. The CCD receives input photons. The weak fluorescence signal acquisition device in the endoscope imaging system is mainly composed of the CCD, the pre-amplification module, the analog signal processing module, the power driving module, the A / D, the digital signal processor, the data acquisition card, the data caching module and other components. The CCD receives the input photons (weak fluorescence signals), and conducts signal amplification, analog signal processing, power driving and other processing operations on the weak fluorescence signals, and the weak fluorescence signals are acquired, stored and output. The weak fluorescence signal acquisition device has excellent practicality.
Description
technical field [0001] The invention relates to the technical field of endoscope imaging systems, in particular to a weak fluorescent signal acquisition device for an endoscope imaging system. Background technique [0002] At present, a medical endoscope imaging system includes an endoscope, a remote light source connected through an optical cable, and a control unit connected through a power and data cable. With the development of science and technology, the existing image acquisition devices can no longer fully meet the needs of use, so it is necessary to develop a device that can realize the acquisition of weak fluorescent signals. Contents of the invention [0003] Purpose of the invention: In view of the deficiencies in the prior art, the purpose of the present invention is to provide a weak fluorescent signal acquisition device for an endoscopic imaging system, in order to realize narrow-band light-excited autofluorescence imaging by collecting weak fluorescent signa...
