Abstract:
1. An arrangement in a treatment device for monitoring the power delivered by a photon channeling element, comprising: an integrating chamber to receive an output end of said photon channeling element and one or more optical surfaces positioned to reflect at least a portion of the laser-light exiting said photon channeling element, said one or more optical surfaces positioned at substantially normal incidence to a beam centerline of said laser-light, wherein said integrating chamber is configured to collect at least a portion of the laser-light reflected from said optical surfaces; a sensor, said sensor being in optical contact with at least a portion of said integrating chamber, such that said sensor is exposed only to laser-light indirectly reflected from said optical surfaces, wherein said integrating chamber is adapted to scatter and re-scatter light reflected from said optical surfaces within the integrating chamber in a manner to provide a substantially evenly distributed ambient light illuminating said integrating chamber; and an output end from which the laser-light is delivered to a treatment surface.
