Infrared detecting circuit. |
摘要 |
<p>An infrared detecting circuit (20) is provided with an electric current detecting circuit wherein a constant voltage is applied to an infrared sensor (21) from a constant voltage source. The electric current flowing into the infrared sensor (21) is detected as an infrared detecting signal, in order to enable the detection of an incident dose of infrared light with high accuracy in a wide temperature range. <IMAGE></p> |
