摘要： An in-line laser beam waist analyzer system includes an optical prism that picks off a portion of a second surface reflection from either a laser processing focus lens or a protective debris shield for the processing lens and directs that focused light to a pixelated detector. This provides real time monitoring of the focused laser beam while it is processing material by welding, cutting, drilling, scribing or marking, without disrupting the process.

摘要： A system and method for profiling a focused laser beam of a galvanometer scanner which includes an attenuation optic, wherein the attenuation optic includes a first meniscus lens to face the focused laser beam source, wherein the first meniscus lens is tilted at a fixed angle of incidence relative to an optical axis of the focused laser beam and a second meniscus lens between the first meniscus lens and a pixelated detector, wherein the second meniscus lens is tilted at substantially the same fixed angle of incidence relative to the optical axis of the focused laser beam as the first meniscus lens and is rotated about 90° relative to the first meniscus lens.

摘要： 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.

摘要： A method and apparatus for improving measurements of a laser beam in a laser imaging system. The method includes, positioning an apodizing filter having a transmission profile that approaches a maximum at its edges between a pixelated detector and a laser source. The method further includes, emitting a laser beam from the laser source onto the apodizing filter and transmitting a portion of the laser incident upon the apodizing filter to the pixelated detector in accordance with the transmission profile of the apodizing filter such that the signal-to-noise ratio of the portion of the laser incident upon the pixelated detector is improved. The apodizing filter may be selected from a linear apodizing filter, a radial apodizing filter and a prism apodizing filter.
