Abstract: An infrared Raman device is capable of switching and performing Raman measurement and first infrared measurement on a sample. The infrared Raman device includes an objective lens for Raman measurement; a first observation lens for infrared measurement; a laser light source that generates laser light; a first infrared light source that generates first infrared light; and a mirror. The mirror is disposed at time of the Raman measurement to reflect the laser light to cause the laser light to pass through the objective lens for Raman measurement and reflect Raman light generated from the sample by the laser light that passes through the objective lens for Raman measurement and radiated to the sample. The Raman light passes back through the objective lens for Raman measurement.

Abstract: A method of determining an optical spectrum for a sample substance includes splitting a source beam into a reference beam and a sample beam, periodically modulating the intensity of the beams out of phase of each other, directing the reference beam through a reference substance and the sample beam through the sample substance. The beams are then recombined, and a single detector detects the intensity difference at the modulation frequency to determine the spectrum of the sample substance.

Abstract: 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.

Abstract: Methods, systems and devices are described that enable measurement and characterization of complex laser pulses by relying on three interferograms that are measured simultaneously. The described three-phase spectral interferometry (3 PSI) can meet the growing demand for optical recorders with long record and 1 ps or finer resolution. An example three-phase interferometric system includes a three-output optical splitter with a first input port to receive the input optical signal, a second input port to receive a reference optical signal with one or more unknown spectral characteristics. The three output ports of the optical splitter produce interferograms that correspond to relative phase shifts of substantially 120 degrees. Detectors are positioned to receive and measure the interferograms, which allows determination of the amplitude and phase of the input optical signal with very high accuracy. The described techniques include may improvements in the alignment, calibration and signal retrieval procedures associated with the 3PSI system.
