Abstract

The invention relates to a shutter type spectrum transmittance tester and a testing method. The shutter type spectrum transmittance tester comprises a monochromatic light source, a light filter switching device, a lens, a star point hole, a half mirror, a reflector set, a light signal receiving and detecting device, a data collecting device and a main control computer. The light filter switching device, the lens, the star point hole and the half mirror are sequentially arranged on an emergent light path of the monochromatic light source, the half mirror divides light beams entering the half mirror into transmission light and reflected light, and the transmission light and the reflected light are converged to the light signal receiving and detecting device after passing through an optical system to be detected and the reflector set. The data collecting device is connected with the light signal receiving and detecting device and the light filter switching device respectively, and the main control computer is connected with the data collecting device and the monochromatic light source respectively. The shutter type spectrum transmittance tester solves the problem of limitation of the size of optical systems capable of being tested by a spectrophotometer and poor light source frequency modulation stability.

Description

technical field [0001] The invention belongs to the field of photoelectric testing, and relates to an automatic testing device and method for the spectral transmittance of an optical system, in particular to a single detector to realize the energy collection of multi-channel homologous optical signals, so as to measure the spectral transmittance of the optical system Automatic continuous testing device and method. Background technique [0002] When measuring various optical cameras, in order to ensure the detection ability of the camera in a specific wavelength range, it is necessary to evaluate its spectral response characteristics. In addition to obtaining the spectral response curve of the CCD, it is also necessary to obtain the spectral response of the matching optical imaging system. Response function, which determines the spectral response capability and range of the camera and verifies that it is as designed. [0003] The transmittance test of the optical system is u...
