Abstract:
The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device which is connected to the detector arrangement, the filter arrangement has at least a first filter, the suspect filter, which is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band (58), at least one second filter, the reference filter(s), which is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s) (RBl and RB2), and where the detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO.

Abstract:
Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.

Abstract:
A method of determining lighting contributions of elements of a lighting component includes obtaining optical data representative of light output of the lighting component. Relative intensity data may be calculated from the optical data, and may indicate intensity differences in the light output of the lighting component as compared to that of a reference component. An optical property of an element of the lighting component is determined based on a comparison of the optical data with that of the reference component, where the reference component includes at least one reference element. Related systems and apparatus are also discussed.
