【Abstract】 The error in the temperature field and density field measurement with laser holographic interferometry is discussed. The sources of error and methods of error calculation are proposed. The defect of the beam expander and chromatic aberrations are found to be the main error sources. Methods for dorrecting the error are given.更多还原
