A New Design for Laser Warning System
نویسنده
چکیده
A new design of laser warning system is proposed. This novel system is composed of an optical antenna based on fiber bundle and a spatially modulated stationary Michelson interferometer as Fourier transform device. The interferometer has no moving parts, which can distinguish laser from background noise and from other non-coherent radiation such as flares, sunlight, and lighting. Based on Fourier transform spectrometer principle, we can timely get laser source spectrum information from interference pattern. We describe the configuration and operating principle of the system in detail. The experiments show that the performances of the system are practical. Key-Words: Laser warning system, Coherent detection, Fourier Transform, Fiber bundle, DSP, Non-scanning

Analysis of New Laser Warning Technologies to Propose a New Optical Subsystem
In this paper, after a brief overview on laser warning system (LWS), a new structure for an optical array that is used in its optical subsystem is introduced. According to the laser threats’ wavelengths (0.5 – 1.6 µm) and our desirable field of view (FOV), we used 6 lenses for gathering the incident radiation and then optimized the optical array. Lenses’ radius, their se...
