【Abstract】 This article presents a measurement method of real-time wavelength and arriving direction of wide band tunable pulsed-laser under harsh circumstance using grating diffraction principle. The experimental opto-electronic system is been designed, through which wavelength and incoming direction data of tunable pulsed laser are obtained. These information are processed and analyzed with DSP chip TMS320VC5509 The experimental results prove that the laser wavelength resolution with 10nm and direction resolution in 1° can obtained in real time. Wavelength range is from 400nm to 1100nm, Filed of View with 22.5° this measurement technology can be used in the novel a generation tunable laser warning receiver.更多还原
