Abstract

The invention provides a single-tube resolution testing device of a super-second-generation low-light level image intensifier. The device comprises an optic guide rail, a sliding pedestal, a mechanical adjusting module, a light source, a light source uniform attenuation and objective image projection module, an image tube clamp, and a monocular microscope module. The sliding pedestal, the mechanical adjusting module, and the image tube clamp are divided into left and right parts including a left sliding pedestal and a right sliding pedestal, a left mechanical adjusting module and a right mechanical adjusting module, and a left image tube clamp and the right image tube clamp. The optic guide rail, the sliding pedestal, and the mechanical adjusting module are arranged from bottom to top; the light source, the light source uniform attenuation and objective image projection module, the left image tube clamp, and the monocular microscope module are arranged on the mechanical adjusting module successively from left to right in a central coaxial mode. All parts are connected by bolts. The left sliding pedestal and the right sliding pedestal enable the parts arranged on the left sliding pedestal and the right sliding pedestal to move or locked on the optical guide rail.

Description

technical field [0001] The invention relates to a low-light test technology, in particular to a low-light image intensifier single-tube resolution test transposition. Background technique [0002] Resolution is one of the important performance parameters of low-light image intensifiers. Currently, the test method for resolution is mainly based on human eye observation. In China, with the continuous expansion of the night vision technology market, the research on the resolution test of the image tube is getting more and more popular, but there is no single-tube resolution test equipment specifically for the ultra-second-generation low-light image intensifier. Contents of the invention [0003] The object of the present invention is to provide a single-tube resolution test device of a super-second-generation low-light image intensifier, which can realize the resolution test of a single-tube image tube of a super-second-generation low-light image intensifier. The adjustment ...
