Optical design of dual mode imaging infrared system in MWIR and LWIR spectral bands

Optimization process is the one of the most crucial part of optical design due to it's including weight, size and performance parameters. Current developments in optical and electronical technology reduce the size and weight of these systems and improve image performance. In this study, optical design of small diameter dual mode imaging infrared system will be summarized. Optical design is including prisms to provide wide field of regard which are rotated in roll axis to scan area. Optical design is also including a filter to split long-wave infrared and mid-wave infrared spectrums from each other. At the end optical design results and analysis will be given.
