Abstract

PURPOSE:To observe an infrared-ray generating body which moves at a high speed in a far-distance area and generates weak infrared rays in an enlarged state by automatically tracking the body by mounting an infrared detector and telescope on a revolving frame and revolving the frame toward the body. CONSTITUTION:Detecting outputs from infrared sensors DT1-DT4 which are equally divided in X- and Y-axis directions (lateral and vertical direction) are amplified by means of high-gain amplifiers A1-A4 and detecting level signals S1-S4 are sent to an automatic control section U2. The section U2 compares detecting levels S1-S4 with each other by means of comparator circuit XC1, XC2, YC1 and YC2 and further compares the signals obtained from the comparison by means of comparator circuits XC and YC and the circuits XC and YC respectively generate an X- and Y-axis direction leading control signals Sx and Sy and send the signals to a revolving frame section U3 through mode change-over switch circuits SW1 and SW2. These signals turn the frame U3 mounted with the sensor DT and a telescope U4 toward a target so as to automatically track the target by driving servo motors MX and MY through servo amplifiers AX and AY.
