<P>PROBLEM TO BE SOLVED: To provide an infrared detection apparatus of a simple constitution for measuring a wide temperature range, reducing the effects of variations in an operation point, and achieving a low cost. <P>SOLUTION: The infrared detection apparatus is provided with a reference voltage generating means 101 for generating a prescribed reference voltage; an ambient temperature compensation means 102 for receiving the impression of the reference voltage from the reference voltage generating means 101 and outputting a signal for compensating for an ambient temperature; a first amplification means 103 for amplifying the signal outputted from the ambient temperature compensation means 102; an infrared detection means 104 for receiving the impression of the signal outputted from the first amplification means 103 and converting infrared radiant energy into an electric signal; and a second amplification means 105 for amplifying the signal outputted from the infrared detection means 104. <P>COPYRIGHT: (C)2004,JPO |
