Application of array detectors in imaging spectrometer polarization detection technique
摘要
Abstract
In order to apply near-infrared focal plane array detectors in imaging spectrometer polarization instruments to get the high-quality image information , a new type of imaging spectrometer detection techniques on basis of near -infrared focal plane array detectors was proposed combining with a photo-elastic modulator-based imaging spectro-polarimeter ( PEM-ISP) .A FPA-640 ×512 InGaAs focal plane array detector was used as an optical detector receiving element and a high -speed field-programmable gate array ( FPGA ) was used as the signal processing unit to get fast acquisition and parallel processing of the optical signal and meet the other requirements of the high-speed, real-time signal transmission and processing .The data collected by the high-speed A/D was storaged in the expanding outside SRAM of the FPGA in order to ensure the data integrity .And then, the data was ultimately transmitted to the host computer via USB for image restoration . The experimental results show that the system can be applied to PEM-ISP, achieve accurate detection and acquisition of the measurement signals and get complete image information .关键词
