Abstract: The invention relates to methods of assessing the polymorphic form of a substance by assessing Raman-shifted radiation scattered by a particle of the substance. The method is useful, for example, for assessing particle sizes and size distributions in mixtures containing both particles of the substance and other materials. The invention also relates to methods of selecting and controlling polymorph formation by illuminating a material with non-resonant (i.e., non-absorbed) laser radiation as it is thermally driven through a phase transition temperature.

Abstract: The disclosure is generally directed to a method and apparatus for providing an image of a sample. The apparatus includes an illuminating source for transmitting photons to a sample. The transmitted photons illuminate the sample or are scattered upon reaching the sample. A lens collects the scattered photons and transmits the scattered photons to a tunable filter for forming an image. The illuminating photons traveling from the illuminating source to the sample do not pass through the lens.

Abstract: A method and apparatus for imaging biological objects. A SERS surface is provided having enhancing structures uniformly distributed on the surface. T he surface includes a two dimensional area of at least 5 x 105 nm. The enhancin g structures may have a size, in at least one dimension of height, width and length, ranging from 100 nm to 1000 nm. A biological material is deposited o n the SERS surface. The biological material on the SERS surface is illuminated using a monochromatic light source producing Raman scattered photons. The Raman scattered photons are filtered using a tunable filter into a plurality of predetermined wavelength bands. A two-dimensional array detector detects the filtered Raman scattered photons, in a spatially accurate manner. The results of filtering and detecting steps are combined to produce a plurality of spectrally resolved Raman images of the biological material.

Abstract: The disclosure relates to systems and method for chemical imaging of microarrays. In one embodiment, the disclosure relates to a system for simultaneous spectral imaging of a plurality of samples arranged on an array. The system includes an illumination source for providing illuminating photons to said plurality of samples, the illuminating photons interacting with each of the plurality of samples to emit interacted photons; an array for receiving said plurality of samples, the array having an external dimension such that the samples are within a simultaneous field of view of the optical device; an optical device for collecting the interacted photons and directing the photons to an imaging device, the imaging device simultaneously forming a plurality of images corresponding to each of the plurality of samples.

Abstract: The disclosure relates to method and apparatus for interactive hyperspectral image subtraction. In one embodiment, the disclosure relates to a method for obtaining a spectral image of a first specie from a frame of a plurality of pixels defining a composition of the first specie with a second specie. The method may include (i) identifying, for each of the first and second species, an appropriate Raman wavelength; (ii) defining at least one background wavelength for the frame; (iii) identifying pixels defined only by background wavelength; (iv) identifying pixels defined only by the first specie or the second specie; (v) identifying the remaining pixels, the remaining pixels defined by at least a combination of the first and second species; and (vi) forming a spectral image for the first specie.
