Abstract :
Infrared imaging system with high resolution and large depth of focus play an important role in optical remote sensors. In this paper we design a phase mask infrared imaging system with ZEMAX optical software. The phase mask reduces the sensitivity of the infrared imaging system to the change of defocus. The infrared imaging system combines optical coding and image restoration to provide improved imaging performance and large depth of focus.
