    Abstract: Disclosed is an apparatus and method for obtaining images using coherent anti-stokes Raman scattering. The apparatus for obtaining images using coherent anti-stokes Raman scattering according to the present invention comprises: a pump light source and a stokes light source that irradiate pump light and stokes light on a sample to generate anti-stokes light having anti-stokes frequency; a reference light source that generates reference light; and an image obtaining unit that obtains the images of the sample using a change in phase of the reference light due to a change in the refractive index of the sample in the vicinity of the anti-stokes frequency. Thereby, the present invention can provide the apparatus for obtaining images using coherent anti-stokes Raman scattering that is not affected by a non-resonant background signal phenomenon, strong resistance against noise even in a weak signal, and has excellent sensitivity and resolution.

    Abstract: Cross over (S560) in a genetic algorithm (128) is adapted for deriving an optimal mask (S540), or set of segments of a line. Each mask of a chromosome is subject to cross over with the respective mask of the other parent. Any overlapping part, whether a filtering (320) or pass-through part (350), is retained in the child (334) to preserve commonality. The part is preferably, potentially extended, according to one parent or the other, as decided pseudo-randomly (430). In a preferred application, spectrums of candidate blood constituents are masked for fitting to ensemble spectrums of test blood samples (S610, S620). The developed masks are applicable to constituent spectrums to create masked spectrums (S710) which are then applicable to an actual blood sample to be analyzed (S720).

    Abstract: Macroscopic and microscopic samples are imaged through a spectral filter operable into the short wave infrared, e.g., to approximately 3200 nm. The sample is illuminated for reflective, transmissive, fluorescent and/or Raman imaging by a laser or metal-halide arc beam. The filter has tunable birefringent retarders distributed rotationally and stacked in stages leading up to a selection polarizer. Image forming optics and CCD cameras collect the luminance of each pixel in the spatially resolved image, at multiple wavelengths to which the filter is tuned successively. The filter stages have comb shaped transmission characteristics. Two filter stages with distinctly different characteristics can be cascaded, one or both being tunable. The combined transmission characteristic has narrow passbands where the bandpass peaks of the stages coincide and wide free spectral range where the peaks do not coincide. Embodiments are disclosed for forensic analysis, material composition and morphology, chemical compound identification and detection of biological species.
