title: Influences of pyramid prism deflection on inversion of wind velocity and temperature in a novel static polarization wind imaging interferometer.
abstract: The principle of the novel static polarization wind imaging interferometer (NSPWII) [Acta Opt. Sin. 28, 700 (2008)] based on a pyramid prism is described. Since the measured wind velocity and temperature depend on the transmittance of the pyramid prism, the deflection of the prism introduced by vibration would produce some measuring errors. In this paper, with an assumed deflection case, we analyze its influence on the derived wind velocity and temperature theoretically. The relative error of the inversion temperature and variety of the inversion velocity as they changed with the deflection angle are discussed.
