The Testing Technology And Simulation Of Dynamic Target Based On The Digital Micromirror Device

The testing technology and simulation of dynamic target based on the digital micro-mirror device, On the ground in the laboratory simulated visible light CCD aerial camera working condition:Computer simulation to generate dynamic target,through the DMD imaging projection play a high-speed dynamic high resolution image, after three sets of parallel light pipe transmission image generation big field of infinite targets at the same time. By scanning CCD aerial cameras this goal, Finally through the camera image and original image contrast analysis of the CCD aerial camera is in line with the computer standard reconnaissance flights.In this paper, the simulation test technology not only guarantees the scans the required high resolution CCD camera image quality requirements, Also addresses the need of the contradiction between large field of view and optical structure limits. Develop matching software support for three screen with frequency transmission, To achieve high resolution large image simulation, transmission and display. Control work station can make an accurate assessment of work load and the imaging quality;outfield flight test technology model is set up; plan guidance to identification test. This technique is applied to CCD aerial camera test simulation system, for aviation camera detection has important significance, Provide technical support for aircraft reconnaissance load test.
