Abstract: The invention discloses a Trace Microanalysis Microscope System for high throughput screening. A multimodal imaging sensor arrangement acquires color, multispectral, hyperspectral and multi-directional polarized imaging, independently and in combinations thereof. In one aspect of this disclosure, the multimodal acquisition is combined with a plurality of sample illumination modes, further expanding the dimensionality of the generated data. In another aspect of this invention, machine learning-based methods combining and comparing a-priori data with the acquired multimodal data space, provide unique identifiers for the composition of the analyzed target objects. In yet another aspect of this invention, projection mapping of the identified compositional features navigates secondary sampling for subsequent analyses.

Abstract: This disclosure is directed to pulsed spectropolarimeters for conducting remote, non-perturbative measurements of the local magnetic field, density and temperature fields of a magnetized plasma medium. In one aspect, a pulsed spectropolarimeter includes a light source emitting a polarized light pulse having sufficiently narrow spatial extent at a prescribed wavelength and a light gathering optical system including a light gathering optic having an optic axis directed toward the medium and positioned to collect and collimate a predetermined solid angle of the scattered emission by the pulse in the backward direction, toward the source, while preserving the polarization state of the emission. A proportion of the emission is redirected to a spectrometer detector to determine the spectral distribution of the emission. A second optical collection and spectrometer system collects emission other than backscatter localized to the intersection of the pulse trajectory and the focus of this collection system.

Abstract: A system for a high resolution optical spectrum analyzer (OSA) using various optical configurations to reduce polarization dependent loss (PDL) is disclosed. The system may include a birefringent element to receive an input optical beam. The birefringent element may then split the optical beam into at least two exit beams. The system may also include an optical configuration comprising at least one optical element. The optical configuration may receive the at least two exit beams from the birefringent element and transform at least one of the two exit beams using the at least one optical element to provide two parallel beams with parallel polarizations. The optical configuration may then output the two parallel beams with parallel polarizations to a downstream optical element, such as a diffraction grating, or other optical element.

Abstract: In a Fourier-transform spectroscopy apparatus, a scanning mirror is arranged on a light path of scanning light. The scanning mirror delays or advances the scanning light with respect to reference light according to the rotational angle of the scanning mirror from its initial position. A spectroscopic spectrum generating unit generates an interferogram based on the intensity of the detection target light obtained from the detection target, and Fourier transforms the interferogram thus generated. The spectroscopic spectrum generating unit corrects the nonlinearity of the group delay between an envelope of the reference light and an envelope of the scanning light, and corrects the nonlinearity of the phase shift between the respective envelopes.
