The image intensifier is a optical instrument that can enhance the low radiant intensity, and is used to make the faint object contour visible to the naked eye. The main components of an image intensifier typically include image sensors, optical lenses, night vision tubes, circuits, and power supplies.
1. Image sensor The image sensor is the most important component of an image intensifier, which can convert weak light signals into electrical signals and transmit them to the circuit processor. At present, the main image sensors used are CMOS and CCD, with slightly different imaging effects. However, the main principle is to convert light images into electrical signals.
2. Optical lens Optical lens is one of the important components of image intensifier, which can perform operations such as focusing, splitting, and lens combination on incident light. By adjusting the shape and size of the lens, the light imaging can be clearer and the image quality can be improved.
3. The night vision tube is the core part of the image intensifier, which can enhance the electronic signal of light and improve the light intensity in low light intensity environments at night. The working principle of a night vision tube is to convert the received photons into electronic signals through methods such as photoelectric multiplication and cathode and anode condensation. After being enhanced and amplified by an electronic lens, they are then converted into visible light signals through a fluorescent layer.
4. The circuit and power supply of the image intensifier are the control center of the image intensifier. The circuit is mainly responsible for the amplification control, signal processing, and output tasks of the night vision tube. The power supply is the guarantee for the normal operation of the image intensifier, including DC power, AC power, and batteries. The circuit and power supply are also important factors to ensure the stable operation of the image intensifier. To sum up, image intensifier is an advanced optical instrument composed of several important components, including image sensor, optical lens, night vision tube, circuit and power supply. The synergy of these components makes the image intensifier have the advantages of powerful enhancement of low radiant intensity, enhancement of image quality, improvement of night vision ability, etc. It is widely used in military, police, medical, scientific research and many other fields.
