Title: Heat ray detector
Inventor: AKIYAMA TOSHIRO
IPC: G01V8/12
Filed: 1990-01-22
Abstract: PURPOSE:To improve the low frequency response to the gentle change of heat rays by mounting a heat ray detection circuit detecting a gentle temp. change and a differentiation circuit using mirror integration in a feedback circuit. CONSTITUTION:The quantity of heat rays incident to a thermopile 1 is changed in a trapezoidal shape by the approach and separation of a human body. This quantity of heat rays has a waveform almost equal to the change of the quantity of incident heat rays shown as the input of a discrimination circuit part 7 by the band amplification having an extremely large differentiation constant, that is, band amplification amplified from an extremely low frequency band in an amplifying circuit part 2. Subsequently, the discrimination circuit 7 discriminates that the human body is detected when input voltage exceeds the negative set value shown by the low discrimination level in a drawing to output discrimination output and, therefore, the discrimination output is issued during a period from the approach time of the human body to the separation time thereof. By this method, low frequency response is improved and stable detection can be performed.
