Abstract: Methods and systems for obtaining biochemical and/or structural information relating to tissues using Raman spectroscopy. Polarised light is directed to tissue using a probe. The light is reflected from the tissue, producing Raman scattering. The Raman scattering is collected by the system and split into two polarised components. The two polarised components are simultaneously imaged using a spectrometer to produce two Raman spectra. The Raman spectra are then processed and analysed using a computer program to obtain biochemical and/or structural information relating to the tissue.

Abstract: Systems and methods which provide a high-throughput point source light coupling structure (120) implementing a condenser (122) configured according to one or more condenser (122) configuration rules are described. Embodiments of a high-throughput point source light coupling structure (120) utilize a birefringent plate (341, 342) configuration in combination with a condenser (122) and point source (121) to provide a light coupler structure (120) for a birefringent-static-Fourier transform interferometer implementation. According to some examples, the optical axis of a first and second birefringent plate (341, 342) of a birefringent plate (341, 342) configuration are not in the same plane. The condenser (122) of the high-throughput point source light coupling structure (120) of embodiments is provided in a defined (e.g., spaced, relational, etc.) relationship with respect to the point source (121) and/or a camera lens (131) used in capturing an interference pattern generated by the light coupling structure (120). The high-throughput point source light coupling structure (120) herein may be provided as external accessories for processor-based mobile devices (130) having image capturing capabilities.

Abstract: A method for detecting at least one property of a plant product, the method including: directing source light including ultraviolet (UV) light at UV wavelengths and polarized visible and/or near-infrared (VIS/NIR) light at VIS/NIR wavelengths onto a region of the plant product; blocking the polarized VIS/NIR light of the source light, and blocking polarized specular reflection from the region of the plant product, from being transmitted to a visible and/or near-infrared (VIS/NIR) spectrometer; and transmitting a portion of emitted light caused by fluorescence and/or diffuse reflection from the region of the plant product to the visible and/or near-infrared (VIS/NIR) spectrometer.

Abstract: Techniques, devices and methods for discriminating a target from a background material without optimizing directly on the target are provided. The devices and methods can generate pass bands of single or multiple wavelengths of variable shape and intensity, and can also select and control the shape of the pass band profiles to improve the detection of targets of interest.
