    摘要: A method of increasing the spatial uniformity of the detected intensity of a beam of light from a laser in a system including the laser and a light detector. In one embodiment the method includes the steps of generating a beam of light with the laser; and moving the beam of light and the light detector relative to each other, such that the detector averages the spatial intensity of the beam of light over time. In another embodiment the invention relates to a system for increasing the detected spatial uniformity of the intensity of a beam of light. In one embodiment the system comprises a light detector; a laser source for generating the beam of light; and a means for moving the beam of light and the detector relative to one another such that the detector averages the intensity of the light beam over time.
