2、 CONSTRUCTION OF A PORTABLE CONFOCAL MICROSCOPE FOR IMAGING HUMAN TISSUE IN VIVOABSTRACTA confocal scanning microscope is capable of noninvasively imaging thin sections within a thick transparent or translucent obj

3、ect with high resolution and contrast. The use of confocal optical technology can observe the fine structure and biochemical composition of cells 200-micron deep from the surface, thus it is very suitable for pathologica

4、l diagnosis of skin diseases. We have built a real time confocal scanning microscope for reflectance imaging of human skin. The whole system includes the optical module, scanning modules, synchronization circuit, compute

5、r processing and the interface modules. A polygon mirror is utilized together with a galvanometer to realize a 1000x1000 image at a frame rate of 10 fps, covering a scan field of 1.4mm x1.4mm. A pair of lateral stepping

6、motors are employed which extends the filed-of-view to 7mm x 7mm. By using z-stepping motors, axial scan is realized with the resolution of 3 microns. NI image acquisition card PCI-1410 can process the image information

7、detected by the anavalanche photodiode (APD) and the horizontal and vertical sync signals generated by synchronization circuit, then output video signal. The entire system is controlled using LabVIEW software.Key words:
