Paper Abstract

This paper describes a design of sun-tracking warning demonstration system in solar blind UV. After analyzing of the system structure and guide line of the sun-tracking warning system in solar blind UV, the key techniques of the sun-tracking UV warning system are discussed and designed, including the optical system, UV filter module, optical modulation system, UV detectors and its sun-tracking servo. A total reflect Cassegrain UV optical system with simple structure, reliable performance and high-quality imaging ability is designed and manufactured. In order to enhance the received SNR and process the signal easily, an optical UV filter and an optical modulation reticle are used to filter and modulate the target's direct signals to alternating signal. Functional experiments show that sun-tracking warning system needs better UV filter module whose total stopband rejection should be higher than 10-10.
