Abstract
A light emitting apparatus including an emitter configured to emit electromagnetic radiation of a predetermined spectrum including visible light and infrared light, and a plurality of focusing chambers, each focusing chamber including an aperture, wherein light from the emitter passes successively through at least a first of the chambers and an aperture of the first chamber, and through a second of the chambers and an aperture of the second chamber before exiting the apparatus.
Claims22
A light emitting apparatus comprising:
- an emitter configured to emit electromagnetic radiation of a predetermined spectrum including visible light and infrared light;
- and
- a plurality of focusing chambers, each focusing chamber including an aperture, wherein light from the emitter passes successively through at least a first of the chambers and an aperture of the first chamber, and through a second of the chambers and an aperture of the second chamber before exiting the apparatus.
A method of focusing a beam of light comprising:
- aligning an emitter, configured to emit electromagnetic radiation of a predetermined spectrum, with a plurality of focusing chambers;
- providing each focusing chamber with an aperture;
- and
- directing light from the emitter successively through the apertures of the focusing chambers.
1 more element
A target stand comprising:
- at least two extendable members;
- springs normally biasing each of the extendable members out of the target stand;
- a latching mechanism for maintaining the extendable members against the springs and within the target stand;
- and
- at least one light receiving module associated with each extendable member and adapted to provide an electronic signal to the latching mechanism upon receiving a beam of electromagnetic radiation of a predetermined spectrum so that, upon a beam of electromagnetic radiation being received by the light receiving module, the latching mechanism releases the extendable member associated with the light receiving module.
