Abstract: The improved system for remote chemical analysis of this invention includes a quartz halogen bulb as a source of infrared light, quartz fibers leading to and from a sample cell, a non-collinear thallium arsenic selenide, AOTF to perform spectral analysis and a lead selenide detector, Both the AOTF and the detector are interfaced with a microcomputer. Under the control of the microcomputer, this equipment gathers and interprets transmission spectra obtained through the passage of infrared light through the sample cell. Microcomputer interface provides rapid random-access to the RF frequency driving the AOTF, which selects the wavelength of light to be examined and also provides routines for sample averaging and the comparison of various reference spectra. An acousto-optic device mounted in an enclosure which includes input and output crystal fiber connectors is also provided.

Abstract: Using a gas detector (300), photonic radiation is emitted over a first range of frequencies and through a pathway (315). The gas detector includes at least one broadband light source (305), at least one detector (310), and an electronically tunable filter element (320) disposed in the pathway and between the at least one light source and the at least one detector. The electronically tunable filter element allows a window of radiation frequencies to pass through the filter and suppresses other radiation frequencies. The electronically tunable filter clement is tuned to allow different windows of radiation frequencies to pass through the filter. Photonic radiation energy that passes through the tuned electronically tunable filter element and impinges on the detector is measured to form a spectral absorption signature characterizing constituents of gas in the pathway. Related apparatus, systems, techniques, and articles are also described.

Abstract: A spectrometer (100)that provides the ability to combine the advantages of high resolution, compactness, ruggedness, and low-power consumption of Fabry-Perot (FP) tunable filter spectrometer (105), with the multi-channel multiplexing advantage of FT and/or grating/detector array (118,130). The key concept is to design and operate a tunable FP filter in a multiple-order condition. This filter is then followed by a "low-resolution" fixed grating, which disperses the filtered n-order signal into a preferably matched N-element detector array for parallel detection. The spectral resolution in this system is determined by the FP filter, which can be designed to have very high resolution. The N-order parallel detection scheme reduces the total integration or scan time by a factor of N to achieve the same signal to noise ratio (SNR) at the same resolution as the single channel tunable filter method.

Abstract: Spectral measurement devices and methods able to provide EEMs and other spectral measurements. The devices rapidly and specifically illuminate a sample and detect resulting light emanating from the sample. Such devices can use acousto-optic tunable filters (AOTFs) to selectively illuminate the sample with illumination light substantially only in a desired illumination wavelength(s). This provides high detection sensitivity, large measurement dynamic range and scans of the full 400-1000 nm light range (or more) at rates as fast as about 1 second, or even as fast as video rates. In another aspect, methods and systems relating to the analysis of autofluorescence emanating from melanin under long wavelength visible light (VIS) and near infrared (NIR) excitation.
