Abstract: A sensing system comprising a light filtering apparatus configured to pass a first wavelength of light corresponding to an emission spectrum characteristic of Mercury. The sensing system comprises a sensor configured to receive light passed by the light filtering apparatus and produce a sensor response that is indicative of the light passed by the light filtering apparatus. The sensing system comprises a processor configured to use the sensor response to distinguish between light emitted by a fluorescent light source and light emitted by a light emitting diode.

Abstract: A scanning laser projector includes an optical module and projection engine. The optical module includes a laser generator outputting a laser beam, and a movable mirror scanning the laser beam across an exit window defined through the housing in a scanning pattern wider than the exit window such that the laser beam is directed through the exit window in a projection pattern that is smaller than and within the scanning pattern. A first light detector is positioned about a periphery of the exit window such that as the movable mirror scans the laser beam in the scan pattern, at a point in the scan pattern where the laser beam is scanned across an interior of the housing and not through the exit window, the laser beam impinges upon the first light detector. The projection engine adjusts driving of the movable mirror based upon output from the first light detector.

Abstract: The present application discloses an apparatus configured to measure characteristics of high power beams of laser energy used in material processing. In one embodiment, the apparatus includes a housing having a first compartment and a second compartment separated from each other to reduce the transfer of thermal energy between them. Optical modules having optical sensors configured to measure characteristics of the high power beam are mounted in the first compartment. An optical window operative to allow a significant portion of the beam to propagate therethrough is mounted in an intermediate housing member separating the first and second compartments. A removable and replaceable beam dump configured to absorb most of the high power beam is positioned in the second compartment. The removability/replaceability of the beam dump enables operation of the apparatus without active cooling of the beam dump assembly, simplifying the apparatus and protecting the optical sensors in the first compartment.
