Near infrared skylight background measuring instrument
The Near-Infrared Sky Light Background Measurement Instrument (NIRBM) was developed by Anhui Pixel Optical Measurement Technology Co., LTD and The University of Science and Technology of China. The measuring instrument system consists of optics, structure, electronic control, detector, readout electronics and software control.
This product adopts InGaAs detector with 1.7um cut-off wavelength, uses chopper to modulate weak infrared signal to reduce detector and environmental noise, and uses digital phase-locked amplifier to obtain data, which has the advantages of low noise and high calculation accuracy. In addition, the measuring instrument is equipped with semiconductor cooling (TEC), chopper, and reflector, which can rotate from 0 to 180°.
At the same time, this product is equipped with a set of remote automatic control software system based on EPICS and WEB. By communicating with the serial port of STM32 microcontroller, the upper computer controls each hardware module of the device. Based on Web technology, the web page integrates device control, state acquisition, data analysis, alarm display and other functions, constituting an unattended near-infrared sky background measurement system. Main applications: astronomical site survey.
