Device for testing infrared sensor

Abstract

The invention relates to the field of infrared detection, and discloses a device for testing an infrared sensor. The device comprises a rotating part, a motor module, a signal detection module and a counting module, wherein the rotating part is used for driving a to-be-tested infrared sensor to rotate; the motor module is connected with the rotating part for driving the rotating part to rotate; the signal detection module is used for detecting signals sent when a tested infrared sensor detects infrared signals; and the counting module is used for counting the rotating turn number of the rotating part and the times when the signal detection module detects the signals sent by the infrared sensor. Through periodicity rotation of the rotating part and detection on the signals sent when the infrared sensor detects the infrared signals, the device can realize the performance of automatically testing the infrared sensor.

Description

technical field [0001] The invention relates to the field of infrared detection, in particular to a device for testing infrared sensors. Background technique [0002] All objects that exist in nature, such as human beings, fire, ice, etc., all emit infrared rays, but their wavelengths are different due to the temperature of the object. For example, the body temperature of the human body is about 36-37°C, which emits far infrared rays with a peak value of 9-10 microns, and objects heated to 400-700°C can emit mid-infrared rays with a peak value of 3-5 microns. Infrared sensing system is a measurement system using this kind of infrared as the medium, which can be divided into photon detectors and thermal detectors according to the detection mechanism. [0003] After the infrared sensor is produced as a finished product, it needs to be tested for its detection accuracy and service life. At present, there is no equipment that can automatically test the long-term operation of th...

Problems solved by technology

[0003] After the infrared sensor is produced as a finished product, it needs to be tested for its detection accuracy and service life. At present, there is no equipment that can automatically test the long-term operation of the infrared sensor. Instead, it relies on manual testing and manually activates the infrared device. Manually count the number of activations, test results, failure rate, etc., and require manual on-duty. This test method relies on manual operations, so the test efficiency is low, and it is impossible to accurately control the activation interval, activation frequency, etc.
