SYSTEMS AND METHODS FOR ILLUMINATING AND VIEWING OBJECTS

摘要

A light source contains a laser having a radiating facet that radiates light with an intrinsic or acquired intensity profile. The light is received by an optical scrambler comprising a bundle of optical fibers having and input surface and an output surface. The input surface formed by input endings of the optical fibers in the bundle, the input endings of the optical fibers having a position in the input surface defined by a first set of coordinates. The output surface formed by output endings of the optical fibers, the output endings of the optical fibers having a position in the output surface defined by a second set of coordinates, the second set of coordinates being a non-affine transformation of the first set of coordinates. The optical scrambler receives the light with the intensity pattern from the laser at the input surface and radiates light from the output surface having a different intensity profile. The light source may illuminate an object with light from the output surface, and further comprise a camera enabled to produce an image of the object and a display connected to the camera to display the image produced by the camera of the object.

1. A light source, comprising:
a multi-mode laser diode having a radiating facet, the facet radiating light that diverges with a first beam intensity profile having a first shape; a bundle of optical fibers having:
an input surface formed by input endings of the optical fibers in the bundle; andan output surface formed by output endings of the optical fibers in the bundle; wherein the input surface of the bundle of optical fibers receives the light, and the output surface of the bundle of optical fibers emits the light; wherein the light emitted from the output surface diverges with a second beam intensity profile having a second shape, the second shape being different from the first shape; wherein the input endings have a position defined by a first set of coordinates relative to the input surface, and the output endings have a position defined by a second set of coordinates relative to the output surface; wherein a plurality of the output endings are mixed in the output surface in a non-affine manner relative to the input endings in the input surface.
