Abstract

A phase retrieval algorithm which only needs to measure the intensity distribution at two positions was used to reconstruct laser wavefront. It was further applied in high power laser. Results were obtained from the phase retrieval algorithm in the visible band, and the effects of measurement error on the phase retrieval process have been simulated. This algorithm is not sensitive to measurement error, but sensitive to the relative distribution of light intensity.
