Abstract: A system for remotely detecting gas concentration is provided. The system includes a plurality of light sources. At least a first one of the light sources generates light having a first wavelength and a first polarization, and at least a second one of the light sources generates light having a second, different wavelength and a second polarization that is orthogonal to the first polarization. The light from the light sources is placed on a common transmission path, and is directed to a target area by a steering mirror. Light reflected from the target area is received and directed to a detector. The detector provides information regarding the time of arrival and amplitude of the received light, allowing range and gas concentration information to be obtained. In some embodiments the detector is an imaging detector, allowing three-dimensional range information to be obtained from the target area from a single light pulse.

Abstract: Photoluminescence quantum yield (PLQY) testing of quantum dots is described. In one embodiment, a method involves heating a sample including quantum dots and illuminating the sample with a light source. The method involves measuring spectra of luminescence from the illuminated quantum dots of the sample at each of a plurality of temperatures. The method involves measuring each of the plurality of temperatures with a temperature sensor. The PLQY at each of the plurality of temperatures is computed based on the measured spectra. The method further involves computing a relationship between QD emission wavelength of the measured spectra and the plurality of temperatures measured with the temperature sensor. The relationship is used to determine the QD temperature corresponding to each of the PLQY computations. In one embodiment, an integrating sphere moves on a gantry over the samples.
