Abstract
This article presented the design improvement based on the modal frequency shifting method for resolving the structural response excitation of a catadioptric telescope. For the high image quality demand optical system, the positioning stability of optics is crucial. Taking the catadioptric telescope for example, the most sensitive part is the position of secondary mirror within several micrometer tolerance along optical axis. Therefore, the opto-mechanical design for maintaining the positioning of optics while the system suffering from the harsh environmental vibration becomes important.

Currently, Mr. Huang Yi Kai is responsible for the opto-mechanical design, analysis, integration and testing for the remote sensing instrument of earth observation satellite for Taiwan Space Agency (TASA).
For the opto-mechanical design and analsysis, he is committed to the lightweight mirror design, flexure mount design, structural anlaysis and the wavefront error (WFE) prediction for the telescope. In addition, he is dedicated in the assembly (bonding) for optics with the aided of coordinate measurement machine alignment and the WFE measurement with interferometry.
