The effect on the deformation of the primary mirror surface figure of the temperature gradient has been discussed theoretically. And its effect under axis and radial temperature gradient is analyzed when optical axis and support ways of the mirror changed. It has been concluded that the effect on the surface figure of the axis gradient is larger than radial gradient and also found that the deformation is concerned not only with thermal and structural parameter but also directly with the magnitude and direction of the temperature gradient. 2010 IEEE.

The reconnaissance satellite
communication satellite and navigation satellite used in the military applications have played more and more important role in the advanced technique wars and already become the significant support and aid system for military actions. With the development of all kinds of satellites
anti-satellite laser weapons emerge as the times require. The experiments and analyses of laser disturbing CCD (charge coupled detector) in near ground have been studied by many research groups
but their results are not suitable to the case that using laser disturbs the satellite-based detector. Because the distance between the satellite-based detector and the ground is very large
it is difficult to damage it directly. However the optical receive system of satellite detector has large optical gain
so laser disturbing satellite detector is possible. In order to determine its feasibility
the theoretical analyses and experimental study are carried out in the paper. Firstly
the influence factors of laser disturbing satellite detector are analyzed in detail
which including laser power density on the surface of the detector after long distance transmission
and laser power density threshold for disturbing etc. These factors are not only induced by the satellite orbit
but dependence on the following parameters: laser average power in the ground
laser beam quality
tracing and aiming precision and atmospheric transmission. A calculation model is developed by considering all factors which then the power density entering into the detector can be calculated. Secondly
the laser disturbing experiment is performed by using LD (laser diode) with the wavelength 808 nm disturbing CCD 5 kilometer away
which the disturbing threshold value is obtained as 3.5510-4mW/cm2 that coincides with other researcher's results. Finally
using the theoretical model
the energy density of laser on the photosensitive surface of MSTI-3 satellite detector is estimated as about 100mW/cm2
which is largely exceed the disturbing threshold and therefore verify the feasibility of using this kind of laser disturbing the satellite-based detector. According to the results. using the similar laser power density absolutely saturate the requirements to laser disturbing satellite-based detector. If considering the peak power of pulsed laser
even decrease laser average power
it is also possible to damage the detector. This result will provide the reliable evidences to evaluate the effect of laser disturbing satellite-based detector. 2009 SPIE.

Large-aperture telescope can be used in surveying battlefield
researching landform
searching object
real-time monitoring
imaging
detecting and identifying spatial targets and so on. A large-aperture telescope for achieving high resolution power is designed to monitor spatial target and image in real time. Real-time monitoring plays an important role in military conflicts. The orbit parameter of object
quantity
geometrical shape parameter and so on can be obtained by detect spatial target. With the development of optical technology
people require larger aperture in optics-electronic (OE) system. By increasing optical aperture
the ability of collecting light and resolution power in the system can be enhanced. But the support structure of the primary mirror of large-aperture telescope will be a very difficult problem. With the increase of primary mirror aperture
the weight of the primary mirror will become larger than before. The root mean square (rms) of the primary mirror is affected by many factors
such as deadweight
deformation of heat
environment and so on. Due to the primary mirror of telescope is an important component of telescope system. By reducing the weight of primary mirror
precision of the system is ensured. During the designing phase
one can consider the supporting project of the primary mirror synthetically and analyze it roundly according to technical requirement of optical system and the effect factors. The final structural design can be reasonable. In an astronomical telescope
the surface of reflector is an important part for collecting dark radiation of celestial bodies. Its surface shape will have an effect on collecting efficiency of telescope radiant energy directly. So the rms must be very high. Optical system of large aperture
small wavelength and small focus can receive maximal light intensity. For ground-based optical astronomical telescope
the design proposed in the paper can satisfy the requirement of the possible minimum atmosphere seeing at astronomical observatory site and exert the use efficiency of the telescope adequately. So the accuracy of the traditional surface of reflector can assure that 90% of all the light energy can be focused on within the angle diameter range of the minimum atmosphere seeing
then 100% of light energy should be focused on the angle diameter range of minimum atmosphere seeing. Because the rms of mirror is very high
precise surface machining and accurate the support of mirror are very important tasks during designing and manufacturing the telescope. In the paper
various support techniques of a large-aperture telescope primary mirror are discussed and a 3.5 meter telescope system at the Starfire Optical Range (SOR) overviewed simply
