Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0017] according to figure 2 As shown, the ultraviolet image intensifier resolution test device established by the present invention includes an ultraviolet radiation source 6 , a standard ultraviolet test reticle 7 , an ultraviolet optical system and a three-dimensional mobile test stand 8 .

[0018] The ultraviolet radiation source 6 is composed of an ultraviolet lamp, frosted glass and a neutral filter. The wavelength range of the ultraviolet lamp is 200nm to 400nm, which can radiate strong ultraviolet rays. The relationship between the radiation energy and the wavelength can be found in image 3 . The frosted glass is made of quartz glass (ZS-1) transparent to the ultraviolet band. The neutral filter is also made of ZS-1 which transmits the ultraviolet band.

[0019] The base of the standard ultraviolet test reticle 7 is ultr...

Abstract

The invention discloses an ultraviolet image intensifier resolution testing device, which belongs to the performance testing field of photoelectric instruments. The device comprises an ultraviolet light source, a standard ultraviolet test reticle and an ultraviolet optical system. Under the irradiation of the ultraviolet light source, the standard ultraviolet test reticle can form ultraviolet test light beams containing standard reticles; after being collimated through an off-axis parabolic mirror of the ultraviolet optical system, the ultraviolet test light beams are focused on a photocathode face of a tested ultraviolet image intensifier by an imaging objective lens group in the catadioptric way. The problem about test on the resolution of the ultraviolet band image intensifier is solved; indirect technical support for improving the quality of the ultraviolet image intensifier is provided; and the device also has the advantages of no chromatic aberration, low spherical aberration, high test precision, and the like at the same time, and is convenient to use.

Description

technical field [0001] The invention belongs to the field of performance testing of optoelectronic devices or instruments, and mainly relates to an image intensifier performance parameter testing device, in particular to an ultraviolet image intensifier resolution testing device. Background technique [0002] Ultraviolet image intensifier refers to an electric vacuum device that photoelectrically converts and enhances ultraviolet radiation images in the wavelength range of 180nm to 440nm so that the human eye can normally observe the image details. , a microchannel plate for multiplying the converted photoelectron image, a phosphor screen for converting the multiplied photoelectron image into an image observable to human eyes, and a driving power supply for achieving the above conversion. Because the target detection and imaging in the ultraviolet band has important application prospects in the military and paramilitary fields and other high-tech fields, especially the targe...
