The paper introduces a method that uses the video signal digitized processing module to display the stereo image. In the paper, it introduces a realization project using time-division stereo analog display, discusses a realization method of stereo display which uses video signal of twin-channel video synchronous camera and the digital scanning processing chip that bases on the programming under the bus, analyzes the cause of producing the image flicker during the common stereo image display, adopts the advanced PHILIPS MK-9 module to carry out the data acquisition and memory to the video signal, resolves the problem of image flicker by using "multi-field scanning" and "sequential scanning", it can make the observers acquire more comfortable stereo feeling.
By using light as a carrier, the information of voice and data is sent to a receiver through atmosphere, so this system with computer via some interfaces can be applied to link computers into network. This system has shown many advantages on volume weight flexibility, convenience, security and anti- interference. In this paper, firstly, the principle of a laser communication system is introduced, then the performance of LOC, GaAs, AlGaAs semiconductor lasers are presented; moreover, the basis of choosing photo-detector, the characteristic and usage of silicon avalanche photo-detectors, and the threshold detection and false-alarm ratio of the system are presented in detail.
This paper introduces a photoelectric detection system, i.e. the internal surface of the metal tube illuminated by Xenon light through fiber bundle, is imaged on CCD optical receiver by endoscope. The image can be converted to video frequency signal, then this signal can be converted to digital signal by a sampling control system, which processed by a computer. SO the measurement system can clearly display the surface flaws of workspace of complicated construction, and quantitatively measure sorts of flaws by an image processing system.
