This paper analyses and studies the parameter design of a Spatial Heterodyne Spectrometer(SHS). The basic concept and structure of SHS is described and the dependence of resolution limit

power of resolution and spectral range on some critical parameters of optical components including grating parameters

pixels of detector

image lens and so on is introduced. By taking an integrated system design for example

the simulated result is presented. SHS system built and tested in the laboratory

the basic concepts and performance characteristics of the technique have been verified. Experimental results show that the achieved resolving power of the SHS system is 17 700 at 591 nm

and the spectral range is 574~591 nm. These results are coincident with the theoretical results well.
