The stereo microscope generates two independent images of the
same sample spatially separated to provide stereoscopic image
capability. The two images are focused onto CCD chips in color
cameras . Each CCD chip camera generates a video image at 30
frames per second that is then processed by a Video Encoder that
multiplexes the two frames of video data. The resulting data is
output at 60 frames per second (120 fields per second) . The
alternated video image data is processed in the Personal
Computer by a Frame Grabber card that converts the video data
from a television-standard format to a Personal Computer
compatible format. The Personal Computer displays the output of
just one of the two cameras. Accurate measurement of features
that are perpendicular to the plane of the surface are made by
utilizing both video images and special purpose stereoscopic
imaging software. A stereo-ready monitor is employed for live
viewing of the stereoscopic image using special purpose glasses.
