Abstract: Systems and methods relating to a multi-slit hyperspectral imager. The imager is configured with multiple slits that are parallel to one another. Each slit produces its own hyperspectral cube and is limited to a specific wavelength range. The multiple slits produce multiple data sets, obtained in quick succession, for the same section of an area to be imaged. In optical spectrometry applications such as trace gas sensing and quantification, this allows for improved measurement precision. The imager may be used for any gas of interest by adjusting the wavelength range to one that contains absorption features of the targeted gas.

Abstract: A nonlinear optical microscope is provided, including source of a pulsed laser beam; a spatial light modulator for modulating the spatial profile of the pulsed laser beam; an objective for guiding the modulated beam towards a slide intended to carry a specimen; and a detector for collecting signals originating from the specimen, wherein the spatial light modulator is designed to modulate the intensity and/or the phase of the pulsed laser beam on the rear pupil of the objective to produce a beam that is axially extended and confined in one or two lateral directions after focusing by the objective, and wherein the slide is placed on a motorized stage of a histology slide scanner assembly.

Abstract: The biopsy device generally comprises: a cannula body having a longitudinal axis and a probing region extending along the longitudinal axis, the probing region having a sample receiving window defined therein for receiving a sample of a surrounding tissue when performing a biopsy; and a plurality of optical fibers mounted along an exterior portion of the cannula body, each of the plurality of optical fibers having a fiber end in the probing region of the cannula body, at least one of the plurality of optical fibers being adapted to illuminate the surrounding tissue with an optical signal generated by the at least one light generator and at least one of the plurality of optical fibers being adapted to detect an optical signal response with the at least one light detector, the optical signal response being caused by the propagation of the optical signal in the surrounding tissue.
