Abstract:
A method and apparatus for reducing ghost images in a laser imaging system. The method includes, positioning an absorptive neutral density filter, having an optical density (OD) of at least −1, between a pixelated detector and a laser source. The method further includes, emitting a laser beam, from the laser source onto the absorptive neutral density filter, transmitting a portion of the light incident upon a first surface of the absorptive neutral density filter to a second surface of the absorptive neutral density filter, reflecting a portion of light incident upon the second surface of the absorptive neutral density filter and absorbing the reflected portion of light, by the absorptive neutral density filter, to reduce ghost images at the pixelated detector.
