ことを特徴とする赤外線撮像装置。 It basically consists of an optical lens that focuses incident infrared light and forms an image, and a two-dimensional array of imaging elements that photoelectrically converts the formed infrared light image and reads it out as a serial electrical signal. In the infrared imaging device, two flat plates that are substantially transparent to incident infrared light are placed between the optical lens and the imaging element so as to be approximately orthogonal to the optical axis and do not touch each other, and a first means for slightly changing the angle of the second flat plate in the horizontal direction with respect to the optical axis; means for slightly changing the orientation of the second flat plate in the vertical direction with respect to the optical axis; changing the angle of the flat plate; and reading out the image sensor. It is equipped with means for synchronizing the operation of the image sensor, and equivalently four video signal memories with the same number of pixels as the number of pixels of the image sensor.
1. An infrared imaging device comprising means for writing data into one memory and outputting an output video signal from the four memory screens to form one screen having equivalently four times as many pixels.
