How Thermographic Telescope Works？
2023-07-26
Thermographic Telescope is a device used to detect and measure thermal radiation on the surface of objects. It is mainly based on the principle of infrared radiation, which can capture and display the heat distribution image of the object. Here's how a thermal imaging telescope works:
1. The principle of infrared radiation: All objects emit infrared radiation in the form of thermal radiation, and the frequency range of this radiation is usually 3 to 14 microns (called thermal infrared band). The strength of the radiation depends on the temperature and surface properties of the object. Thermal imaging telescopes use this infrared radiation to sense and measure the temperature of objects.
2. Infrared detectors: Thermal imaging telescopes contain a device called an infrared detector. Infrared detectors sense and convert infrared radiation into electrical signals. Different types of infrared detectors have different working principles, such as thermocouples, pyroelectric detectors, semiconductor detectors, etc.
3. Sensor Array: Modern thermographic telescopes are usually equipped with an array of infrared sensors. The array contains many small infrared detectors, each responsible for capturing infrared radiation from a specific area. The electrical signals measured by these detectors are converted into digital signals and sent to the processing unit.
4. Image processing: In the processing unit, the received digital signal is processed into a thermal image. Each pixel represents the detected temperature information of a specific area. These pixels represent temperature differences through color or grayscale levels, creating a thermal imaging image.
5. Display: Thermal imaging images can be displayed on the display screen of the telescope, enabling users to observe and analyze the thermal distribution of objects in real time.
In general, the working principle of thermographic telescope is based on infrared radiation perception and detection technology, which captures the thermal radiation of objects, converts them into digital signals, and further processes and displays them as thermal images. This makes the thermal imaging telescope a very effective tool for detecting and observing the temperature and heat distribution of objects in dark night or low-light environments, even under occlusions such as smoke and clouds.
