The wavefront coding technology is known as a system-level technology which can extend the depth of focus of optical system by innovative optical design and image restoration. This technology can control misfocus related aberrations including misfocus
astigmatism
and Petzval curvature
temperature-related misfocus in digital imaging systems. It can also help optical system tolerate more residual error in optical manufacturing and alignment besides misfocus. The brief introduction of wavefront coding technology and the wavefront coded TMA system under research is presented respectively in part 1 and part 2. The "MTF similarity" is defined to describe the relationship among MTF at different position or different fields in the third part. It is also shown in this part that the MTF similarity of wavefront coded system is much higher than the normal system within a large range. In part 4 comparison between the origin system and the new system with wavefront coding technology is provided after multiple errors are introduced
from which it can be observed that the system with wavefront coding technology can tolerate much bigger error than origin system. The error tolerance is re-distributed according to a new criterion based on MTF similarity. If the MTF similarity is less than a certain value
it can be regarded that the system can tolerate the residual error. The new error tolerance is displayed and it is shown that the wavefront coding technology can also loosen the error distributing besides extended the depth of focus.

A novel design of combination of hybrid system and zoom system in hyperspectral detection imaging is discribed based on the application of harmonic diffractive element (HDE) compared with conventional system. The principles of HDE and infrared zoom hyspectral detection system are presented and the results of a example design are given. It is show that the resolution of this hybrid system is improved and the light power received by Cassegrain system is enlarged. Wavefront aberrations are less than 1/4 wavelength and Modulation Transfer Function in the dual band on each zoom focus location approaches or attains the diffraction limit on 20 cycles/mm.
