Abstract: Laser induced breakdown spectroscopy (LIBS) devices for analysis of geological and related samples, and related methods. In the method, a scanning table having a geological core is moved from a start position to an end position for each position in a plurality of positions of the scanning table corresponding to an e region of interest of the geological core. At each position, laser ablation is performed on the exposed surface of the geological core using an oscillating planar focus laser. Contemporaneously with performing laser ablation on the exposed surface of the geological core, spectroscopy is permitted on the emitted light received by a fiber optic receiver sharing an optical path with the oscillating planar focus laser.

Abstract: A method comprising: generating a pulsed laser beam comprised of non-interfering pulse-pairs having a phase difference, wherein the phase difference changes between each two consecutive cycles of the pulse-pairs; directing the pulsed laser beam at one or more optical resonators, wherein each of the one or more optical resonators is impinged by acoustic waves, to cause the pulsed laser beam to propagate through each of the one or more optical resonators, thereby interfering the pulse-pairs; and calculating shifts in a spectral response of each of the one or more optical resonators based on measuring the interference, wherein the shifts are indicative of a waveform of the acoustic waves.

Abstract: A seamless fumed silica monolithic integrating cavity device tailored to analyzing a flowed sample. The device is configured to facilitate optical measurements taken from a sample flowed through a cavity of the device. The cavity is defined by a fumed silica monolith with the added feature of a fused quartz lining on the surface of the monolith. This provides an intermediate surface that allows for cleaning and reuse of the highly effective diffuse light scattering fumed silica monolith. The lining may be placed under pressure or vacuum to structurally enhance mechanical integrity of the underlying monolith. Thus, continued or reliably repeated use of the device may be appreciated as well as use in more industrial environments that are prone to vibration. Additionally, while well suited for flow-based sample analysis, a valve of the cavity may be utilized for holding a sample in a temporarily static state for measurement.

Abstract: Proposed is a method for quantifying water and lipid contents in turbid media. Methods for quantifying water and lipid contents through non-invasive methods in turbid media in which scattering occurs upon penetration of near-infrared rays have yet to be proposed. In addition, existing apparatuses and methods for measuring body composition use frequency-domain and time-domain diffuse optical spectroscopy or infrared spectroscopy to measure water and lipid contents in tissue, whereby there are limitations that hardware configurations become complicated, and mass production and sales are subject to constraints. To solve such problems, proposed is a method for quantifying water and lipid contents in turbid media using narrowband diffuse reflectance spectroscopy, which uses only a near-infrared band in a range of 900 to 1,000 nm, configured such that the water and lipid contents can be accurately quantified in tissue through a simpler configuration than that in existing methods.

Abstract: This invention provides devices for use in various analytical applications including single-molecule analytical reactions. Methods for detecting analytes optically by propagating optical energy by waveguides within a substrate are provided. Analytical devices are provided which have both shallow and deep waveguides in which illumination light is transported through the deep waveguides and coupled into the shallow waveguides. The shallow waveguides provide evanescent field illumination to analytes, such as single-molecule analytes, within nanometer scale wells. Integrated devices including integrated detectors such as CMOS detectors are included.
