Abstract : In infrared and laser technology applications, use is often made of a number of special optical systems--in their overall layouts, they lose coaxial symmetry characteristics. In terms of system components, one has the appearance of special optical aspects--for example, in laser working technology, it is necessary to use circular cone surfaces to extract good quality ring belt laser beams. In laser scanning systems, it is necessary to use torroidal surface components to carry out rotary scanning. In semiconductor laser systems, it is possible to opt for the use of cylindrical surface lenses and shape corrective components to improve light beam collimation characteristics. In night vision instruments, it is possible to use numerical value apertures associated with Fresnel lens enlargement systems, and so on along these lines. As far as these types of optical systems are concerned, due to their special structures themselves, relying on manual labor makes is extremely difficult to design good results. It is only with the application of computers to the execution of structural parameter automation that one has the best way to resolve problems. However, because this type of system is very different from traditional coaxial spherical systems, a number of new problems will undoubtedly appear with the automatic optimization. This article attempts to put forward methods for solving a number of difficult points in them.
