Abstract

The invention provides a testing evaluation device for a pyroelectric non-refrigeration infrared focal plane detector. The device comprises a light source black body, an adaptive board, a data collection card, a data processing module, a computer system module, and other computer general modules. A block body radiation modulation device is disposed between the light source black body and a non-refrigeration infrared focal plane detector, and is electrically connected with a synchronizing device. The synchronizing device is connected with a data collection pre-triggering device, and the data collection pre-triggering device is electrically connected with the data collection card through an amplification signal outputted by the non-refrigeration infrared focal plane detector. The device achieves the modulation of infrared radiation, meets the requirements of performance test of a pyroelectric detector, solves a problem that the testing and evaluation of the pyroelectric non-refrigeration infrared focal plane detector cannot be carried out in the prior art, enables the scale production of the pyroelectric non-refrigeration infrared focal plane detector to be possible, and reduces the testing cost.

Description

technical field [0001] The invention relates to a test and evaluation device for a pyroelectric uncooled infrared focal plane detector, which belongs to the technical field of infrared imaging systems. Background technique [0002] The infrared focal plane detector component is an important optoelectronic device to obtain the infrared thermal radiation information of the target scene. According to the working temperature of the detector, the devices can be divided into two categories: the refrigerated type whose temperature of the sensitive element of the detector is at or below -100°C during operation, and the non-refrigerated type whose temperature of the sensitive element of the detector is around room temperature during operation. The principle of uncooled infrared focal plane detector (such as figure 1 ) is to convert the infrared radiation 1 of the invisible scene to the human eye through the lens 2 to the infrared focal plane detector 3 into electrical signals of dif...
