Technical field:
The invention belongs to optical technical field, relating to a kind of compact refraction-reflection LONG WAVE INFRARED does not have the thermalization imaging optical system.
Background technology:
Infrared optical system is used more and more widely, and working environment becomes increasingly complex, and is increasingly high to the image quality requirement of infrared optical system, and the high-performance infrared optical system that design can be operated under the severe environmental conditions becomes inevitable.Variation of ambient temperature will cause material change of refractive, system's focal length change, image planes displacement (out of focus), image quality deterioration etc.The thermal instability of this optical system especially with infrared optical system for very, this mainly is that the refractive index of most infrared optical materials is obvious with temperature variation because the thermal stability of infrared optical material is relatively poor.Therefore, in the process of design infrared optical system, must adopt certain compensation technique, make infrared optical system in a bigger ambient temperature range, keep favorable imaging quality to eliminate the influence of temperature effect.
Traditional no thermalization method for designing can be divided three classes: (1) mechanical passive type; (2) dynamo-electric active; (3) PASSIVE OPTICAL formula.Wherein the PASSIVE OPTICAL compensation way is because characteristics such as structure is simple relatively, little in light weight, the system reliability height of size have received great attention.
Catadioptric optical system is because the primary and secondary mirror is shared most of focal power, and helping system does not have the thermalization design; Utilize the catoptron folded optical path, dwindled the volume of camera lens and alleviated quality, length can be accomplished shorter than focal length.In sum, require the compact occasion of lightweight, generally adopt the refractive and reflective optical system design form at infrared optical system.
