Abstract
Official abstract text for this publication.
A long range laser illuminator is disclosed that is suitable for providing illumination for camera systems at ranges up to approximately 20 km. The illuminator incorporates a diverger that allows for a compact, low F-number optical arrangement that improves eye safety by reducing the power density across a primary optical element, such as a spherical or parabolic mirror. The diverger may be located at an end of an optical fiber feed, or between a pair of optical fibers. The diverger may incorporate a diffuser, such as a “top hat” diffuser. The optical fiber feeds may be highly multi mode, to provide for a more even illumination. The illuminator incorporates means for altering a focus of the output light beam, to allow an illuminated spot size to be altered. The illuminator is particularly suitable for use at night, where it may be used alongside a camera system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A long range illuminator comprising: a laser source having a laser power output, an optical feed and a primary optical element having an associated optical area, wherein the optical feed is arranged to transfer a light beam from the laser and provide it to the primary optical element to produce an illuminator output, wherein: the optical feed includes a first optical fibre and a beam diverger, the beam diverger including at least a light diffuser, the…
