Embodiment Construction

[0022] The structure of the anti-strong light interference imaging device of the present invention will be further described in detail in the following embodiments in conjunction with the accompanying drawings.

[0023] figure 1 Shows a specific implementation of the anti-strong light interference imaging device of the present invention, such as figure 1 As shown, it includes: entrance pupil 1, imaging objective lens 2, spatial modulator 3, adapter mirror 4, exit pupil 5, CCD detector 6, video image acquisition and feedback module 7, spatial light modulator control circuit 8 and video Record Module 9.

[0024] Wherein, the spatial light modulator 3 can perform partition modulation on each pixel, so as to reduce the transmittance of the interfering light pixel to zero. Specifically, the video image acquisition and feedback module 7 is connected to the CCD detector 6, and the spatial light modulator control circuit 8 is respectively connected to the video image acquisition and...

Abstract

The invention relates to an imaging device with resistance to strong light interference. The imaging device comprises an imaging objective, a switching mirror and a charge coupled device (CCD) detector in the light path direction in sequence, wherein a spatial light modulator is arranged between the imaging objective and the switching mirror and can perform zone modulation on each pixel to ensure that the transmittance of an interference light pixel is reduced to zero. By the imaging device with the resistance to strong light interference, the spatial light modulator can perform zone modulation and / or independent control on each pixel, so that dynamic imaging under the condition of strong light interference is realized; control accuracy and speed are high; a control mode is simple and reliable; and the imaging device is wide in application prospect and high in using value in the technical fields of dynamic observation, photoelectric guidance and military industry.

Description

technical field [0001] The invention relates to the technical field of photoelectric imaging, in particular to an imaging device capable of resisting strong light interference and a method for using the same. Background technique [0002] A dynamic imaging device in the prior art is generally provided with a CCD detector, and the CCD detector is used to collect video images. In the use and application of this kind of dynamic imaging device, the interference of strong light is the most influential factor on the video image acquisition effect. [0003] The date of authorization announcement is December 22, 2004. The Chinese invention patent with the patent number ZL00110728.3 discloses a device for resisting strong light interference. It uses a CCD area array, an optical filter and a video signal processing system. Within the range of the field of view of the array, a light splitting element is placed to divide the incident light into two paths, one path is the main light pat...
