For demands of optical systems in a off-axis three-mirror camera on the optical-mechanical structure
an appropriate optical-mechanical structure was designed by taking Carbon Fiber Composite(CFC) as the key components of the camera. The weight of CFC in designed camera makes up 32% that of the total system. Furthermore
this optical-mechanical structure is asymmetric
the system spacing in the primary
secondary mirror is 850 mm
and the mirror positioning accuracy demands its interval
eccentric and tilt to be 0.005 mm
0.005 mm
and 5
respectively. The Finite Element method was used to analyze and optimize the design
results show that the optical-mechanical structure has better stiffness
lighter weight
and can meet the requirements of optical system for intervals
eccentrics and tilts. A mechanics environmental test and a thermal vacuum test were performed
and results demonstrate that the optical-mechanical structure in the camera has excellent stability in mechanics
thermal and other environmental conditions
its first order harmonic frequencies are above 120 Hz
and the modulation transfer function is more than 0.2. These results prove that the proposed structure can provide reasonable spatial location and stability for the reflective mirrors in off-axis three-mirror cameras.
