Abstract: A concentration correction system includes an infrared detector and components that produce an aggregate emission of infrared radiation. A mirror assembly includes a mirror and is changeable between a correcting configuration and a measuring configuration. In the correcting configuration, the mirror produces a mirror signal incident on the detector. The mirror assembly also obstructs external body infrared radiation from reaching the detector. In the measuring configuration, the mirror assembly allows the external body infrared radiation onto the detector. A concentration correction method includes receiving external body infrared radiation and simultaneously receiving a first portion of the aggregate emission. A measurement value indicative of concentration is recorded from the detector. A second portion of the aggregate emission reflected with the mirror and produces a mirror signal incident on the detector. A correction value corresponding to the mirror signal is recorded from the detector and used to correct the measurement value.

Abstract: The invention provides an infrared upconversion spectrometer for determining a mid-IR spectrum of received infrared light with a high resolution. The spectrometer applies upconversion to transform light in the mid-IR to the near-IR range where efficient detectors are available. The up-conversion causes divergence of the light, and in addition, the invention applies an extra dispersive element to record a spectrum.

Abstract: A divided pulse nonlinear optical source may be generated by combining nonlinear wave generation techniques with pulse division that can divide a parent pulse into N divided pulses, each divided pulse separate temporally. The N divided pulses can be passed into a nonlinear optical medium to generate an output. The output can include at least one output pulse for each divided pulse. The center wavelengths of each output pulse can be tuned so that each may have a center wavelength that is the same as, or differs from, each other output pulse. In some embodiments, the output pulses may be combined to generate the output. The output can be power scalable and wavelength tunable.

Abstract: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.

Abstract: Soil penetrometers capable of measuring soil reflectance along the direction of insertion of the penetrometer are provided. The penetrometer can house an array of sensors, such as, for example, a Vis-NIR reflectance sensor, a load cell, a displacement sensor, and a moisture sensor. The reflectance data collected using the penetrometer can allow the interpretation and quantification of soil constituents and contaminants at high vertical resolution, such as 3 cm or more.

Abstract: In swept source Raman (SSR) spectroscopy, a swept laser beam illuminates a sample, which inelastically scatters some of the incident light. This inelastically scattered light is shifted in wavelength by an amount called the Raman shift. The Raman-shifted light can be measured with a fixed spectrally selective filter and a detector. The Raman spectrum can be obtained by sweeping the wavelength of the excitation source and, therefore, the Raman shift. The resolution of the Raman spectrum is determined by the filter bandwidth and the frequency resolution of the swept source. An SSR spectrometer can be smaller, more sensitive, and less expensive than a conventional Raman spectrometer because it uses a tunable laser and a fixed filter instead of free-space propagation for spectral separation. Its sensitivity depends on the size of the collection optics. And it can use a nonlinearly swept laser beam thanks to a wavemeter that measures the beam's absolute wavelength during Raman spectrum acquisition.
