Optical camera is a high-precision optical instrument
and the optical lens must be always stable under various environments
so the structural materials of optical camera should have good stability and machining performance characteristics. Generally
the weight of the camera increases with the increasing size of optical camera aperture. The application of carbon fibre reinforced plastic(CFRP) in optical camera can help to improve the situation and meet the requirements of large volume and light weight. In this paper
the properties of several kind of materials used in camera structure were compared
the advantages of CFRP used in optical camera were analyzed
the CFRP application profiles of domestic and international were introduced
and the reason of gap was pointed out. There is a conclusion that CFRP will be widely used in the optical camera in China. 2012 IEEE.

A review of high-speed flow pressure and aerodynamic heating effect on Supersonic missile's dome is given. The dome should have excellent properties in optical
mechanical and chemical characteristics. A design of dome on supersonic mode is described according to tactical guide line of a missile. The dome made of quartz which is about 8mm thick and 141mm in window diameter. To check up the reliability of the dome
a reasonable finite element model (FEM) of dome is established
and a thermal-mechanical Analysis to the dome by finite element software NASTRAN has carried on
through these can obtained the distribution of temperature field and stress field when the speed is 2.3Ma. The results indicated that the stress was concentrated in the joint of the dome end and the Missile Section
and the maximum stress was 16.4Mpa. The stress of other nodes was smaller than the allowable stress of quartz glass. Reference to the results of the analysis
a lightweight revision to the dome structural dimension and a new method of dome fixing have put forward
which can reduce the stress concentration. 2009 SPIE.
