Problems solved by technology
[0006] However, the response speed of the photoelectric radiation sensor is extremely fast, and its response time is usually measured in microseconds or even nanoseconds. The sampling frequency of the current electrical measurement equipment is far from enough to support the detection of such a short time response characteristic. Other applications in photoelectricity The relevant experimental methods of device performance testing may not be able to adapt to the performance indicators of photoelectric radiation sensor products, or the equipment is expensive and the experimental operation is complicated, so it is difficult to apply to the daily inspection and calibration of photoelectric radiation sensors. No valid dedicated equipment

Description
technical field [0001] The invention relates to a photoelectric radiation sensor response time testing device, which belongs to the technical field of sensor detection. Background technique [0002] Solar radiation is the most fundamental energy of atmospheric movement, and the earth-atmosphere system itself emits infrared radiation energy all the time. Therefore, the measurement of the Earth's surface radiation budget is the basis for understanding the Earth's climate system and the impact of humans on climate change. With the deepening understanding of global climate change on human life and survival issues, and the development and utilization of clean energy including solar energy, the importance of solar radiation measurement has become increasingly prominent. [0003] There are many methods for radiation measurement. In solar radiation measurement, the most widely used radiation sensors are pyroelectric radiation sensors and photoelectric radiation sensors. The former...
