とを特徴とする赤外線撮像装置。[Claims for Utility Model Registration] A wide-field optical lens for condensing and imaging incident infrared light, and a two-dimensional array for photoelectrically converting the image of the formed infrared light and further reading it out as a series electric signal. In an infrared imaging device, which basically consists of an infrared detector and a correction circuit that corrects the sensitivity variation of each pixel of the infrared detector, the infrared light from the scene to be imaged is taken in.
An infrared imaging device characterized in that the focus adjustment of the optical lens is shifted to a short distance position, and sensitivity variation data of an infrared detector corresponding to each field of view is incorporated into the correction circuit.
