The field of laser remote sensing and laser detection is becoming a research hot spot. Filter wheel is an important part in the process of remote sensing. The purpose of filter wheel is to choose the proper band wavelength of light to realize the specific functions. The paper made a design scheme of a type of filter wheel component and then did structural analysis under different and strict load cases. These various load cases were used to prove that if the component could be safe during the launching time of the rocket. For the initial design scheme, the situation was not good. After that, the paper made an improved design by using special flexible supports, which had flexible links and support glue. At last, structural analysis was made. The result of analysis showed that the improvement was effective and successful.
