Problems solved by technology

[0013] The current measurement method can only use a large-diameter integrating sphere for high-precision calibration and calculation of partitions. However, the volume and mass of the integrating sphere are relatively large, requiring special drive equipment, requiring large power consumption, and inconvenient installation. Satisfy the confirmation test requirements of the payload before launch and other specific occasions

Abstract

The invention discloses a design of an LED multipoint multi-spectral collimation test light source. The LED multipoint multi-spectral collimation test light source can be used for achieving imaging function tests in different load observation modes, waveband switching function tests, multi-angle function / view field tests, signal-to-noise ratio tests, full-view-field multi-waveband imaging quality qualitative detection, image noise inspection and polarization measurement precision verification. The light source is small in size, light in weight, low in power consumption, safe, reliable, easy to install and detach and capable of adapting to function tests and performance tests on various scenes, function and performance detection can be performed on an atmospheric aerosol multi-angle polarization detector in the whole development process, efficiency is improved, and load development speed is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, and in particular relates to the design of a multi-point multi-spectrum collimation test light source. Background technique [0002] So far, the performance test and calibration of multi-spectral imaging equipment is realized by imaging the large-aperture luminous flux adjustable integrating sphere. The integrating sphere is the most critical equipment for performance test and calibration. Generally, the Calibrations are performed on a regular basis and can all be done in the laboratory. The Atmospheric Aerosol Multi-Angle Polarization Detector is an ultra-wide-angle, multi-band, polarization imaging observation payload. Due to its ultra-wide-angle characteristics, there is no such a large-aperture integrating sphere that can realize the measurement and calibration of the entire imaging area at one time. Although the imaging of the integrating sphere is controlled by the complex ...
