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
