The laser measurement method for detection of the helicopter rotary-wing pyramidal angle has advantages of simple structure, fast respond and high accuracy. This paper presents the detecting principle and the realization of the helicopter rotary-wing pyramidal angle by laser cutting method. Based on previous measurement scheme, a new laser light path structure is designed by using spectroscopes, and the realization for the design of system components of laser light path, signal acquisition and processing, operating and display in host computer is introduced. The simulation experiment proves the system can fully meet the design requirements and runs steadily.
