Abstract

A new method with conical mirror was put forward to detect and orient the laser threaten sources. The intensity distribution of reflecting light interference field was analyzed. The theoretical formula about the relation of wavelength with azimuth angle orientation was given. The interference field with oblique incidence was analyzed based on the idea oblique section cylinder. It is concluded that the ratio of long axis and short axis is linear to angle of incidence. The detecting and orienting system for laser threaten sources was built in the laboratory. This orientation method can realize the all-direction valid warnings to laser threaten sources.
