Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.

Abstract: Provided is a spectrum measurement apparatus including a light source configured to emit light to a sample; a light detector configured to receive light, which is reflected or scattered from, or transmitted through the sample, and to measure an intensity of the received light, and a processor configured to reconstruct a spectrum of the sample for calibration while adjusting a value of a spectrum reconstruction parameter in response to the light detector receiving the light and measuring the intensity of the received light, and to determine an optimal value of the spectrum reconstruction parameter based on a similarity between the reconstructed spectrum of the sample for calibration and an original spectrum of the sample for calibration.

Abstract: Optical analysis systems and methods may be used for analyzing the characteristics, including compositions, of cement additives, which may be used in formulating a cement slurry. For example, a cement additive may be optically interacting with an integrated computational element (“ICE”) configured to detect a characteristic of the cement additive. An output signal may then be generated corresponding to the characteristic of the cement additive detected by the ICE, which may be received and processed with a signal processor to yield a value for the characteristic of the cement additive. The value of the characteristic of the cement additive may then be used to determine an amount of the cement additive for use in producing a cement slurry.

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: A multidimensional spectrometer encodes frequency information into laser pulses so that a frequency insensitive detector may be used to collect data for a multi-dimensional spectrograph only from intensity information and knowledge of a modulation providing the encoding. In one embodiment the frequency encoding may be done by a conventional interferometer greatly simplifying construction of the spectrometer.
