The infrared band is located between the visible light band and the microwave band,compared with visible light,has the characteristics of thermal effect,invisibility and strong penetration.With the rapid development of infrared holography technology using infrared laser as a coherent light source,infrared holography technology has shown incomparable advantages over visible light holography technology in the field of non destructive testing and lensless imaging.In this paper,the development history of infrared holography technology is reviewed,and the research status of infrared digital holography(IRDH),scanning infrared digital holography(SIRDH),and infrared digital holographic microscopy(IRDHM)are introduced.Moreover,the detection advantages and typical applications of infrared holography technology are summarized,and finally the future development trend of infrared holography technology is prospected.
