摘要：

Interference fringes arising from multiple reflections can significantly alter the diffraction patterns of diffractive optical elements. One way to reduce interference effects is by time-integrating the diffraction pattern while frequency sweeping the laser source. This method is especially useful when it is not possible to remove the cover glass from the observation camera.
