1. A system comprising:
- an infrared imaging module comprising a focal plane array (FPA) configured to capture a thermal image of a scene within a field of view (FOV) of the infrared imaging module;
a visible light source configured to project a visible light beam having a beam angle that is narrower than and within the FOV of the infrared imagine module such that the thermal image covers a larger area of the scene than an area to be illuminated by the visible light beam; and
a processor configured to generate alignment guide information based on a location of a subject in the thermal image of the scene relative to the area to be illuminated by the light beam;
wherein the visible light source is configured to be selectively directed based on the alignment guide information to substantially align the visible light source with the subject and project the visible light beam substantially on the subject.

Abstract
Various techniques are disclosed for providing systems for providing alignment guide information to selectively direct a visible light source to substantially align the visible light source with a desired subject and to project a visible light beam substantially on the desired subject. For example, a system may include a small form factor infrared imaging module to capture thermal images of a scene, which may be received by a processor to generate alignment guide information such as a user-viewable image of the scene, a user-viewable cue, and a framing reticle. In another example, such a system may be implemented as a camera. In yet another example, such a system may be implemented as a spotlight.

11. A method of operating a system, the method comprising:
-
capturing, by an infrared imaging module having a focal plane array (FPA), a thermal image of a scene within a field of view (FOV) of the infrared imaging module; generating alignment guide information for aligning a visible light source configured to project a visible light beam having a beam angle that is narrower than and within the FOV of the infrared imaging module such that the thermal image covers a larger area of the scene than an area to be illuminated by the visible light beam; receiving a force to selectively direct the visible light source to substantially align the visible light source with a subject based on the alignment guide information; and projecting a visible light beam from the visible light source substantially on the subject while the visible light source is aligned based on the alignment guide information; wherein the generating of the alignment guide information is based on a location of the subject in the thermal image of the scene relative to the area to be illuminated by the light beam. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
