Abstract: A method for utilizing polarization as a scheme for fluorescence removal from UV Raman spectra collected in a standoff detection scheme has been invented. In this scheme, a linearly polarized ultraviolet (UV) laser interacts with a material on a surface or in a container. The material generates Raman scattering with polarization contributions relative to that of the laser. The material possibly fluoresces as well, but the fluorescence is generally unpolarized. By subtracting a scaled version of the perpendicular component from the parallel component of the returned signal both relative to the laser source polarization—it is possible to generate a spectrum that is fluorescence free and contains the strongest features of the Raman scattered light.

Abstract: There is set forth herein in one embodiment, a structure including a metallic grating having a grating pattern, the metallic grating including a critical dimension. The metallic grating can output a spectral profile when exposed to electromagnetic radiation, the spectral profile having a feature. The grating pattern can be configured so that a change of the critical dimension produces a shift in a value of the feature of the spectral profile. A method can include propagating input electromagnetic radiation onto a metallic grating having a two dimensional periodic grating pattern and measuring a critical dimension of the metallic grating using output electromagnetic radiation from the metallic grating.

The optical information detector includes a light emitter to emit light to a recording medium and a light receiver to receive the light and detects information of the recording medium. The sheet distinguisher distinguishes a type of the recording medium based on the information detected by the optical information detector. The sheet thickness detector includes a displacement gauge to sandwich the recording medium with an opposing member disposed facing the displacement gauge and to move from an initial position thereof and a displacement detector to detect an amount of displacement of the displacement gauge. The sheet thickness detector detects a thickness of the recording medium based on detection results obtained by the displacement detector.

Abstract: Embodiments generally relate to a light source and methods for minimizing temperature sensitivity of a light source light source. In one embodiment a light source includes a light-emitting diode, a light beam having an optical axis, a photodetector and a polarizer. The diode is operatively configured to emit the light beam. The beam splitter, positioned to intercept the light beam, includes a first optical surface operatively configured to reflect a first portion of the light beam and to transmit a second portion of the light beam therethrough. The photodetector is positioned to capture the first portion of the light beam after reflection by the beam splitter and operatively configured to generate photocurrent proportional to an intensity of that captured first portion. The polarizer is positioned between the diode and the beam splitter, and is operatively configured to polarize the light beam along a polarization direction perpendicular to its optical axis.
