| 摘 要： | 依据单元非成像型光谱辐射计的特点,提出了一种单元非成像型红外光谱辐射计的成像光谱数据获取系统.该系统采用在光谱辐射计前端加装扣描装置.结合同步控制器,实现光谱辐射计的空间扫描.利用光谱辐射计提供的接口,完成了采集获得的成像光谱数据的批量定标.该系统可达到500×500像素的空间分解能力,光谱范围667～5 000 cm-1,光谱分辨率为1 cm-1,空间视场角为150°,瞬时视场角为0.3°.将该系统应用于实际的场景光谱数据获取,通过对得到的实验数据分析和比较,说明本文给出的基于非成像光谱辐射计的成像数据获取系统,能够实现实际场景的成像光谱数据获取,能够满足实时性要求不太高的成像光谱数据获取.

| Abstract: | According to the characteristic of single-element detector and non-imaging spectroradiometer, a new imaging FTIR spectroradiometer system was developed for spectral data acquisition This system is composed of a spectroradiometer, a synchronous controller and a scanning device. Using the data interface of spectroradiometer, spectral radiometric calibration can be achieved for the system. The image resolution is 500 x 500 pixels, spectral range is 667-5000 cm(-1), spectral resolution is 1 cm(-1), and space Field of view is 150 degrees, Instant Field of View is 0.3 degrees. Experiments were held for actual data acquisition and data analysis was made. The analysis result indicates that the proposed system is adequate for non-realtime imaging spectral data acquisition |
