Embodiment Construction
[0019] The present invention will be further described below with reference to the specific drawings and embodiments.
[0020] like figure 2 Shown: The PN junction of a diode-type uncooled infrared detector has good temperature characteristics, and its forward voltage decreases with increasing temperature. Therefore, the temperature change of the detector can be detected by measuring the change of the voltage drop across the diode, and then the intensity of the infrared radiation incident on the detector can be obtained. In order to overcome the problem of the conduction voltage drop of the diode infrared detector, eliminate the offset voltage and low-frequency noise, and improve the integration and signal-to-noise ratio of the system, the present invention includes a transistor 2 connected to the negative end of the diode infrared detector 1, and the The drain terminal of the transistor 2 is connected to the negative terminal of the diode infrared detector 1, and the source...
