OPTICAL CONSTRUCTION OF THERMOVISION SCANNING SYSTEM Russian patent published in 2004 - IPC

FIELD: optics.

SUBSTANCE: device has aperture diaphragm, rotating prism with mirror sides and drive, moving mirror with drive, mirror optical system, radiation receiver. Device additionally has ate least first immersion filling space of optical route of optical device and mirror optical system, second immersion which optically connects radiation receiver to mirror optical system, third immersion with possible optical connection between aperture diaphragm and object. Aperture diaphragm is made in form of spectrum filter of elastic film, moving mirror is made in form of echelette, rotating prism with mirror sides and moving echelette are placed in capsules of material conducting infrared radiation, radiation receiver is made in form of pyroelectric crystal and semiconductor shunt placed in same screening case, entrance of device is third immersion optically connected through spectrum filter, through optical device, through mirror optical system, through second immersion, to pyroelectric crystal.

EFFECT: higher resolution of device, quality images of limits of temperature fields of objects.
