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).

The distortion made by optical lens largely affect the measurement accuracy of the large field of view photoelectricity measurement system
according to the theory of aberration in the photoelectricity system
this paper design a series of distortion measurement devices
in connection with the process of distortion correction in photoelectricity system
establish the related mathmatics model
make the real time distortion correction by the method of software compensation. The experimental results demonstrate the method decrease the measurement error made by the photoelectricity system distortion
after the compensation
in tatal field of view
the systematic measurement error is less than 0.5 picture element. 2010 IEEE.

Computer-generated hologram (CGH) is an effective way to compensate wavefront in null test of aspheric surfaces and freeform surfaces. Our strategies of CGH design and fabrication for optical testing are presented
and an experiment demonstrating the compensation results of CGH and null lens is also reported. In order to design complex CGH
software was developed
with which we can design a CGH including three sections: main section for compensating wavefront in null test
alignment section for adjusting the relative position between CGH and interferometer
and fiducial section for projecting fiducial marks around the optics under test. The design result is represented in GDS II format file which could drive a laser-direct-writer- machine to fabricate a photomask. Then
a 1:1 replication process is applied to duplicate the patterns from photomask to a parallel optical substrate whose surface is error better than /60 rms. Finally
an off-axis aspheric surface was tested with CGH and null lens respectively. The test result with CGH (0.019rms) is almost the same as the result with null lens (0.020 rms). This experiment also demonstrated that fiducial marks projected by CGH can be used to guide the alignment of the optics and measurement of its off-axis distance. 2010 Copyright SPIE - The International Society for Optical Engineering.
