Abstract: Optical fibers are utilized to provide high efficiency, spatially resolved coupling of light from collection optics to an imaging spectrometer. In particular, a micro lens array may be utilized to couple light from multiple spatial locations into individual optical fibers. At the opposite end of the fiber bundle, the fibers are packed tightly together to send the light into an imaging spectrograph. The light that enters this spectrograph maintains its spatial separation, for instance, along the array dimension and is spectrally dispersed, for instance, along a dimension orthogonal to the array dimension. This spatially separated, wavelength resolved light can then be recorded on a two dimensional detector such as a CCD camera.

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: Input light, such as from an optical sensor or stimulus-wavelength converter, includes one or more light or dark sub-bands. The input light is transmitted, such as through a transmissive layer or transmission component, to obtain effects due to transmission with lateral variation. A detector can, for example, obtain spectral information or other photon energy information about the sub-bands due to lateral variation. For each light or dark sub-band, a transmission component can, for example, provide a respective light or dark spot, and spot position can be used to obtain spectral information such as absolute wavelength or wavelength change. A photosensing component can sense or detect transmitted light or output photons, such as with a photosensor array or a position-sensitive detector. Circuitry can use photosensed quantities to obtain, e.g. a differential signal or information about time of wavelength change.

Abstract: A wavelength detecting apparatus capable of detecting the main wavelength of the light coming into an image capture apparatus and a focus detecting apparatus using the same are disclosed. The wavelength detecting apparatus may include a spectral unit which separates the incoming light according to the respective wavelengths, and may focus the separated light onto a sensor. The main wavelength can be determined based on the wavelength distribution sensed by the sensor. The determined wavelength can be used to further determine amount of adjustment to be made to the defocus amount to compensate for the chromatic aberration associated with the wavelength of the light illuminating the source.

Abstract: A method and apparatus is disclosed for measurement of probe light frequency. The apparatus includes an optical spectrometer comprised of a medium of rapidly changing circular birefringence. The circular birefringent medium changes the polarization of probe light an amount that is dependent upon probe light frequency. Thus probe light frequency is deduced by analyzing probe light polarization after it propagates through the birefringent medium. The birefringent medium is constructed from a gaseous substance and a magnetic field, where the gaseous substance has one or more absorption lines near the probe light frequency. The magnetic field permeates the gaseous substance and shifts the frequency of the absorption line(s) by the Zeeman effect. The method includes probe light emitted from a transmitter, which scatters off of a target, then the scattered probe light is collected and transmitted through the optical spectrometer where frequency is measured. With measurement of probe light frequency, a variety of information about the target can be deduced.

In the path of the coupled in light beams at least one controllable microstructured element is provided, allowing to switch beam paths within the optical arrangement.
