In this system , we employed a newly developed holographic filed concave grating as splitting beams element , as well as multi - channel photodetector - ccd ( charge coupled devices ) as spectrum detection . these all solidified the foundation of measurement ; microcomputer control make the system automatic 采用新型的全息平場(chǎng)凹面光柵作為分光元件,并引入多通道光電探測(cè)器件ccd進(jìn)行光譜信號(hào)探測(cè),為光譜反射率的測(cè)量準(zhǔn)備了物質(zhì)條件;采用微型計(jì)算機(jī)控制,達(dá)到自動(dòng)化測(cè)量。
