随着激光技术的快速发展,推扫相机的激光干扰问题倍受关注。推扫相机一般有较高的角分辨率,口径大焦距长造价高,若按照对等要求进行干扰实验研究,其技术难度大实验费用高。针对激光对推扫相机干扰效果评价的难题,从推扫相机成像原理和激光对推扫相机干扰机理入手,提出了一个推扫相机激光干扰等效缩比模型,并通过实验对该模型进行了验证。实验表明:在推扫相机F数不变的前提下,保持相同的入瞳激光功率和积分时间,激光对缩比相机与原相机具有相同的干扰效应,即在两相机像面上的激光干扰面积基本相同。该研究成果可应用于激光对推扫相机干扰效果评价和相机激光防护研究等方面。
With the rapid development of laser technology, the issue of laser interference of push-scan cameras has drawn much attention. Push-scan cameras generally have a higher angular resolution, high caliber long focal length, high cost, if the interference in accordance with the requirements of experimental research, the technical difficulty of high experimental costs. In order to solve the problem of the interference effect evaluation of the laser on the push-scan camera, this paper proposes a laser interference equivalent reduction model of the push-to-scan camera from the imaging principle of the push-scan camera and the interference mechanism of the laser on the push-pull camera. verification. Experiments show that the same entrance pupil laser power and integration time are maintained under the same F number of push-scan camera. The laser-contracting camera and the original camera have the same interference effect, that is, the laser interference on the image plane of the two cameras The area is basically the same. The research results can be applied to the evaluation of laser interference effects on push-scan cameras and camera laser protection and so on.
