OPTICAL POWER METER FOR SAFE OPERATION OF OPTICAL WIRELESS POWER SYSTEMS

A system for measuring the power of a laser beam, comprising an essentially opaque enclosure, from which the laser beam is directed through an exit aperture. The enclosure contains a beam splitter configured to transmit a major part of the laser beam through the exit aperture, and to reflect a minor...

Beschreibung
Zusammenfassung:	A system for measuring the power of a laser beam, comprising an essentially opaque enclosure, from which the laser beam is directed through an exit aperture. The enclosure contains a beam splitter configured to transmit a major part of the laser beam through the exit aperture, and to reflect a minor part of the laser beam; a diffuser element positioned such that the reflected minor part of the laser beam impinges thereon; at least one detector element in optical communication with the diffuser element, the detector element providing a signal in response to the diffused light of the minor part of the laser beam impinging thereon; and an absorber element positioned such that that part of any light entering the enclosure through the exit aperture and reflected by the beam splitter, impinges on the absorber element, and is essentially absorbed.
