Abstract: A spark spectrometry for inclusions content distribution on the surface of large size metallic materials, comprising the following steps: analyzing the surface of large-size metallic materials by spark discharge continuous excitation scanning, obtaining a mixture intensity distribution data of the solid solution and inclusions of an element on the surface of the large-size metallic materials; the relative frequency distribution diagram of spectral intensity is subjected to peak fitting of normal distribution and Gumbel distribution, obtaining an extreme value distribution data of spectral intensity of the inclusions; a size information of the inclusions in a small sample and that of the largest inclusions are correlated with the spectral intensity distribution data of inclusions, obtaining a result of content distribution of the inclusions on the surface of the large size metallic materials. The invention can quickly obtain accurate distribution information of inclusions of various elements on the surface of metallic materials.

Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.

Abstract: Handheld, broadband terahertz (THz) scanners, housings therefor and imaging systems are provided. The scanner may comprise a 2-Dimensional (2D) gimbaled mirror for beam steering. The 2D gimbaled mirror may comprise a single mirror mounted in a frame, a first motor and a second motor. The first motor and the second motor may be coupled to the frame. The mirror may be rotatable in a first axis of rotation and a second axis of rotation to scan light on a target in two dimensions. The first motor corresponds to the first axis and the second motor corresponding to the second axis. The 2D gimbaled mirror may be positioned within the housing such that the single mirror is positioned at a focus of a focusing lens. The focusing lens may be fixed within a housing. The scanner may also comprise a terahertz emitter and detector.

Abstract: A light detection module has N optical channels, each with an optical filter, a detector, and an amplifier; and an N×1 switch with N input ports each connected to one corresponding output port of each channel to receive an amplified detector output corresponding to a filtered optical intensity incident on that detector. The switch cycles between channels, connecting each amplified detector output in turn to the output port. An ADC samples a time dependent optical intensity signal from the switch, generating a corresponding ADC digital signal output. A microcontroller, connected to the N×1 switch and the ADC, controls acquisition by the ADC to provide a digital voltage data stream from each channel; making the average optical intensity value characterizing the voltage data stream available from each channel at a digital output port of the microcontroller, as N data values, characterizing the light incident on the N channels of the module.
