Continuous attenuation system used for energy simulation in optical scene

Abstract

The invention discloses a continuous attenuation system used for energy simulation in an optical scene. According to the invention, an infrared imaging target simulator tests performance of a seeker system by simulating an infrared target in the condition of a laboratory; an energy continuous attenuation system is the most important part and comprises a high-temperature black body (1), a heat insulation cover (2), a light source mirror group 1 (3), a connection plate (4), a light source mirror group 2 (5), an optical gradually-changing attenuation sheet and a driving system (6); and via the energy continuous attenuation system, uniform irradiation of energy on the surface of a target source and quick and continuous attenuation of output energy can be achieved. Thus, it can be achieved that the target source can be used for simulating gray level of the optical scene and a target used for testing performance of the seeker system. In this way, while uniform irradiation of light beams on the surface of the target source is achieved, continuous adjustment of energy on the surface of the target source can be achieved.

Description

technical field [0001] The invention belongs to the technical field of target simulation, and mainly relates to a continuous attenuation system for optical scene energy simulation. Background technique [0002] With the development of infrared imaging guided weapons, the target simulator is required to provide more realistic target and scene images. As an important part of the target simulator, the energy simulation of optical targets and scenes can provide real-time and accurate target and scene radiation sources for the seeker sensor, so that the ability of target capture and tracking of the seeker system can be tested through simulation experiments. This will not only reduce the cost of testing the performance of the seeker system, but also greatly shorten the development cycle of the weapon. Therefore, how to realize the accurate simulation of optical target and scene radiant energy is of great significance to the development of infrared imaging guided weapons. [0003...

AI Technical Summary

Problems solved by technology

However, since the attenuation magnifications of the 6 attenuators and the exposure time of the 9 gears of the electronic shutter of the CCD camera are determined values ​​that are different from each other, and the energy attenuation process is carried out one by one on the 6 mutually intermittent attenuators, this causes energy loss. There is a certain degree of quantization phenomenon in the change, and the accuracy of the continuous change of energy cannot be guaranteed

From this point of view, the existing technology has not yet solved the problem of continuous regulation of the surface energy of the target source
