Abstract

Principle of coherent detection of wide spectrum and pulsed laser wavelength is introduced based on a reflection gate and a high speed linear detector. Signal detecting method is theoretically discussed in the strong sun shine. Formulas for calculating the laser power

sensitivity

S/N ratio and wavelength resolution are also given. ZEMAX is used to simulate the system

providing the guides for elements selection. Theoretical analysis and system simulation show that it is feasible to measure far and short pulsed laser wavelength with this project.
