Abstract:
A process for ablating a matrix of features in a desired object, the process comprising the steps of:a) supplying non-collimated coherent light, from a radiation source, to illuminate a first reflective mirror;b) reflecting the supplied coherent light from the first reflective mirror to a rear surface of a desired area of a collimating component for collimating the supplied coherent light, with the collimating component comprising one of a collimating lens, a refractive component, a diffractive component and a holographic component;c) emitting collimated coherent light from a front surface of the collimating component to illuminate a desired imaging segment of an imaging element comprising one of a holographic element, a diffractive element and a binary mask element, the imaging element comprising a series of individual imaging segments which, when illuminated with a collimated coherent light, produce an image for ablating a corresponding feature in a desired object located at a working distance from the imaging element;d) providing a table for registering the desired object at the working distance from the imaging element; andrepeating at least steps (a) through (c) a plurality of times to illuminate desired individual imaging segments of the imaging element with collimated coherent light from the radiation source to ablate the array matrix of features in the desired object.
