Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to an ultraviolet solar blind detector. Background Technology

[0002] An ultraviolet detector is a sensor that converts one form of electromagnetic radiation signal into another form of signal that is easily received and processed. A photodetector utilizes the photoelectric effect to convert optical radiation into an electrical signal. The photoelectric effect can be divided into the external photoelectric effect and the internal photoelectric effect. In the external photoelectric effect, photons excite a photocathode to generate photoelectrons, which are then collected by external electrodes. The obtained optical signal (current, etc.) is the received radiation conversion value.

[0003] Existing technologies already include relevant detection methods, such as the authorized announcement number CN101533868B, a heterogeneous pn junction solar-blind ultraviolet detector, and the publication number CN209356666U, a marine search and orientation system based on a solar-blind ultraviolet fixed-focus imaging system.

[0004] If a solar-blind ultraviolet detection and warning system is installed on an aircraft, when a missile attacks, the warning system can detect the solar-blind radiation signal in the missile's exhaust plume several kilometers away from the aircraft. Based on the image's position on the detector, the missile's location information can be obtained in advance, allowing the aircraft to take self-defense actions. However, the significant vibrations on the aircraft body make the related processing circuits connected to the detector prone to damage, resulting in a short service life. Therefore, this application proposes an ultraviolet solar-blind detector, providing a new technical solution to address the aforementioned technical problems. Utility Model Content
