A reimaging F/1.0 long-wavelength infrared optical system is proposed. The design has a flexible opto-mechanical layout. The design process is as follows. Firstly
the catadioptric reimaging system consists of two reflecting mirrors and a relay lenses. Two reflecting mirrors make up of the first imaging system and are therefore free of chromatic aberrations
while low dispersion lenses were used in the reimaging system
so the optical system do not need achromatic design for a high image quality. Then
to correct high-order aberrations resulting from large relative aperture
more parameters need to be used with aspheric or diffractive surfaces due to modern optic technology development. Here
aspheric is selected for easily manufacture. Finally
the design is completed with the help of ZEMAX software. The effective focal length of the objective is 120mm and the field of view (FOV) is 4. The simulated final design shows adequate image quality and the modulation transfer function (MTF) is close to diffraction limit. The effect of the surrounding environmental temperature is analyzed using the concept of thermal defocusing
and the thermal compensation is discussed. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

A design method of aspherical surface for panoramic imaging system with two mirrors using multi-populations genetic algorithms is proposed. Astigmatism induced by mirrors may significantly compromise image resolution. To solve this problem
we induced algebraic expression of astigmatism in panoramic imager based on generalized Coddington equation and theory of geometric optics. Then
we propose an optimization process for mirror profile design to eliminate astigmatism and provide purposely-designed projection formula with aid of MPGA. A series of polynomial expressions of aspherical surfaces are obtained and procedures of the design are presented. In order to facilitate ray tracing and aberration calculation
even asphere surface model is obtained by using of hybrid schemes combining MPGA and damped least squares. Finally
a prototype of the catadioptric panoramic imager has been developed and panoramic ring image is obtained. 2009 SPIE.

The magnitude requirement of space target detecting determines that the image of detecting telescope should have several performances: small spots
the wider field of view
small 80% encircled energy diameter and good MTF(Modulation transfer function). So the aperture and field of view of optical system have some demands accordingly. The larger aperture
the more extensive range which the telescope searches. Now most of ground telescopes whose apertures are from 500mm to 1000mm is on-axis optical system
the more energy that telescope collects and higher magnitude the telescope detects
so wide field of view becomes the most importance problem. To obtain large relative aperture and wide field of view
the paper introduces a catadioptric telescope with small aperture aspheric refractive corrector
whose conic surface will be used to remove the aberrations due to large relative aperture and wide field of view. As to the optical system
there is only one aspheric refractive corrector
and it is relatively easy for manufacturing because of its concave figure and normal material. The paper gives the example
and optimizes this optical system with ZEMAX program. And then the paper provides a specific analysis program for testing the aspheric refractive corrector. The aperture of this optical system is 750mm
and its relative aperture is 0.82
and the field of view is 3.6 diameter(diagonal). Its structure is simple and the image quality is also very good. 2009 SPIE.
