Paper Abstract

A Transmissive differential image motion monitor (DIMM) optical system is introduced, which composed of two identical transmissive optical systems. This two transmissive optical system is composed of two pupil required by DIMM. Compared with traditional reflective DIMM optical system, this new type of DIMM system has a simple structure, small size, light weight, easy assembly and adjustment, easy to carry, is more suitable for field work. In order to satisfy the requirement of observation both at daytime and night .we use cut-off filter in this system to separate the bright sky background from the small stellar target an. Then the system can work throughout the day and night without interrupt. The spectral bandwidth of the final design is 650nm-880nm, pupil diameter is 100mm, and focal length is 2300mm, the design result reveals that the image quality is good; the strehl ratio is above 0.4 after tolerances allocate, which can meet the system requirements. The system can detect star above 4 magnitude in the day time, which can meet the requirements of the system observation at daytime and night.
