成像光谱仪编程选择波段数据采集系统的研究

STUDY ON DATA ACQUISITION SYSTEM OF IMAGING SPECTROMETER WITH PROGRAMABLE BANDS

随着成像光谱仪的发展,遥感数据量越来越大,这对电子学系统中的数据采集、传输和处理带来了一定的困难。基于目前技术和数据的实用性两方面考虑,采用编程选择波段的方法能够很好地解决数据量日益增大的问题,国内外的一些方案中已经对此有了一定的设想,即通过遥控指令改变波段数目、光谱取样间隔或波段的重组,这一切都要求有一个灵活性强、通用性好的数据采集系统,能够对不同的选择情况正确地收集用户所需的数据。文中对数据采集的可行性进行了研究,并提出了一个较为容易实现的方案。

With the development of Imaging Spectrometer(IR), the data volume of remote becomes more huge, and the data acquisiton, transmission and handing become more diffcult. Based oh the current technology and the practicality of data, the programmble -selecting - bands method, which changes the numbers of bands, spectrum sample interval or realigning of bands by remote - controlled commamds, can resolve the problem of huge data volume. This paper states the feasibility study on this method for data acquistion and presents an easy - realizable plan.
