摘要

空间外差光谱技术（SHSSpatial Heterodyne Spectroscopy）综合了光栅衍射与空间调制干涉两种技术特点。仪器的系统平场对应零空间频率干涉条纹，通过改变光栅Littrow角与刻线周期，可以设计为任意波长值。本文探讨了空间外差光谱仪系统平场的定标原理，设计了可调谐激光导入消散斑积分球定标方法及定标装置，定标结果表明仪器的实际平场波长比理论设计值向短波方向漂移了约0.05nm，满足仪器设计要求。

Abstract

SHS is a novel technology which shares the advantages of grating and spatially modulated interferometry. The zero frequency of SHS produce a flat-field interferogram

and it could be modulated to any wavelength by changing the gratings littrow angle and line density. The principles of zero frequency calibration is discussed in this paper

and a new zero frequency calibration device is presented

which is a integrating sphere eliminating speckle and the tunable laser being introduced. The calibration result suggests that the instruments zero frequency drifted 0.05nm toward shortwave compared to theoretic value

which meet the design requirements.
