Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

Abstract: A method of obtaining a measurement signal representative of the particle size distributions in nanocrystal suspensions that includes a step of providing a first light beam along a first axis to a first micro-retarder array to generate polarization wavefront shaped light. The shaped light is applied to an objective configured to focus two orthogonally polarized components of the polarization wavefront shaped light to produce first and second axially offset foci along the first axis. A sample having particles in suspension is disposed in one foci to produce a measurement optical signal having phase and intensity values corresponding to at least some of the particles in suspension. The method also includes determining intensity and quantitative phase information as a function of time based on the optical signals.

Abstract: An optical filter may include a first reflector and a second reflector. The first reflector may include a plurality of first gratings having a first sub-wavelength dimension and being arranged to recur at a first interval in a first direction. The second reflector may be spaced apart from the first reflector and include a plurality of second gratings having a second sub-wavelength dimension and arranged to recur at a second interval in a direction parallel to the first direction. The first reflector and the second reflector may include different materials or different geometric structures from each other. Accordingly, it is easy to adjust the transmission wavelength characteristics of the optical filter.

Abstract: An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image from the tooth and a second spectral range for exciting a fluorescence image from the tooth. A polarizing beamsplitter in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor, wherein the second polarization state is orthogonal to the first polarization state. A first lens in the return path directs image-bearing light from the tooth toward the sensor, and obtains image data from the portion of the light having the second polarization state. A long-pass filter in the return path attenuates light in the second spectral range.

Abstract: To measure homodyne interference with a CARS microscope, a supercontinuum beam is used as a light source. A supercontinuum beam is generated using a nonlinear optical fiber that has normal dispersion in which the coherence between pulses is maintained. As the phases of the interference components of detected beams are the same between pulses, it is possible to integrate the interference components and thus improve the signal-noise ratio.

Abstract: Systems and methods for hyperspectral imaging are described. In one implementation, a hyperspectral imaging system includes a sample holder configured to hold a sample, an illumination system, and a detection system. The illumination system includes a light source configured to emit excitation light having one or more wavelengths, and a first set of optical elements that include a first spatial light modulator (SLM), at least one lens, and at least one dispersive element. The illumination system is configured to structure the excitation light into a predetermined two-dimensional pattern at a conjugate plane of a focal plane in the sample, spectrally disperse the structured excitation light in a first lateral direction, and illuminate the sample in an excitation pattern with the one or more wavelengths dispersed in the first lateral direction.
