An Advanced Microscope System Based on the Intelligent Automatic Focusing

XU Sheng, LI Jian wei (Open Laboratory of Optoelectronic Technology & System,National Committee of Education, Chongqing University, Chongqing 400044,China)  
WT5,5”BZ]On the basis of introduction and analysis for the technical development and present state of electronic focusing system at home and abroad,an integral technical scheme for automatic focusing based on SSPD(Self Scanning Photodiode array) and 8098 single chip microprocessor is proposed.A focusing criterion algorithm based on image high frequency component statistics is given.The automatic focusing of the reflection type and transmittance type optical microscopes is performed on this basis.The other related problems such as stability of light source and stepping motor driving which are related to the system reliability are also discussed.
