摘要： A compact, portable Raman spectrometer makes fast, sensitive standoff measurements at little to no risk of eye injury or igniting the materials being probed. This spectrometer uses differential Raman spectroscopy and ambient light measurements to measure point-and-shoot Raman signatures of dark or highly fluorescent materials at distances of 1 cm to 10 m or more. It scans the Raman pump beam(s) across the sample to reduce the risk of unduly heating or igniting the sample. Beam scanning also transforms the spectrometer into an instrument with a lower effective safety classification, reducing the risk of eye injury. The spectrometer's long standoff range automatic focusing make it easier to identify chemicals through clear and translucent obstacles, such as flow tubes, windows, and containers. And the spectrometer's components are light and small enough to be packaged in a handheld housing or housing suitable for a small robot to carry.

摘要： A radio frequency heating system includes a radio frequency heating chamber, a fluorescence temperature measuring transmitter, and a central control unit connected to the fluorescence temperature measuring transmitter. A radio frequency heating container is arranged at the bottom of the radio frequency heating chamber. The radio frequency heating container comprises a fluorescent material with temperature-sensitive fluorescent characteristics, which is excitable by excitation light to produce fluorescence. A light path is provided between the radio frequency heating container and the fluorescence temperature measuring transmitter. The fluorescence temperature measuring transmitter includes a light emitting device for generating excitation light and a driving circuit thereof, a photoelectric converter device for receiving fluorescence, and a signal processing and output circuit for processing output signals of the photoelectric converter device.

摘要： Examples of an integrated active fiber optic temperature measuring device are disclosed. The integrated temperature measuring device comprises a fiber optic probe and an optoelectronic circuitry integrated into a single device which is then individually calibrated. The fiber optic probe has a fiber bundle with an active material at the tip of the probe. The optoelectronic circuitry is connected to the fiber optic probe. The optoelectronic circuitry includes a light source configured to provide an excitation light to the active material, a detector to detect the emitted light, a processing unit configured to determine a temperature based on a change in an emission intensity at a single wavelength range or the change in intensity ratio of two or more wavelength ranges, a lifetime decay, or a shift in emission wavelength peak of the emitted light, and a calibration means configured to calibrate the integrated active fiber optic temperature sensor.

摘要： A thermally luminescent temperature sensor with a rare earth emitter having a first selective electromagnetic light energy emission band and a second selective electromagnetic light energy emission band in which the rare earth emitter converts thermal energy to electromagnetic light energy within the first and second selective energy emission bands. The sensor also has a selective optical detector in optical communication with the rare earth emitter, wherein the selective optical detector independently detects each the first and second selective electromagnetic light energy emission bands. Lastly, the thermally luminescent temperature sensor determines the temperature based on the electromagnetic light energy measured within the first and second selective energy emission bands relative to each other. Optionally additional emission bands may be used in the evaluation of the temperature.
