Electric-Optical (EO) imaging systems are modern systems, especially the one consists of aspheric optics and
image processing called wavefront coding system. The design concept of this kind system is totally different from
the traditional image system. The trade-off between the complexity of the image deconvolution and the depth of
focus extended should be considered. So we establish a simulation model consisting of optical optimization design,
system signal-to-noise ratio analysis and recovered image evaluation. The data can be exchanged among them. This
simulation tools will be very useful in system design process.
The results of design effort for infrared zoom systems using all reflective aspheric surfaces are described. Issues such as
the paraxial design theory and aberration balancing are discussed in detail. Two all reflective zoom optical systems are
disclosed clearly. Both of them are to be used with uncooled infrared detectors. The first design is an unobscured three
mirror zoom system without any intermediate image, and the second is a three mirror system with central obscuration
which forms an intermediate image. With the design theory further developed, this kind of systems can be designed for
cooled infrared detectors, for which cold stop matching is an important issue.
