英文摘要 | The increased demand for detection of dim targets in deep space and the rapid development of low threshold space-based sensors have required greater suppression performance of stay light and higher test accuracy. A stray light test station based on Point Source Transmittance (PST) is built. The station allows an measuring aperture up to 1 m and waveband from the visible to the infrared. In the station, the turntable instrument is allowed to scan ±110° in azimuth, and ±15° in picth. The test station is all black with dimensions of 28 m×8 m×9 m. In order to control light scattered from the collimator, the primary mirror with less than 2 nm RMS roughness is manufactured. A double cylindrical chamber is employed to direct and attenuate the scattered light from the system. In addition, a clean room in 1 000 class is utilized to filter air to reduce light scattered from particles in the air. Analysis and measurements show that the test station can measure point PST as low as 10-7at visible wavelengths, and 10-6at infrared wavelengths. Its test accuracy |lg(measurement value /true value)| is less than 0.5. © 2017, Science Press. All right reserved.
