    Abstract: A photo-thermal interferometric spectroscopy system is disclosed that provides information about a chemical at a remote location. A first light source assembly is included that emits a first beam. The first beam has one or more wavelengths that interact with the chemical and change a refractive index of the chemical. A second laser produces a second beam. The second beam interacts with the chemical resulting in a third beam with a phase change that corresponds with the change of the refractive index of the chemical. A detector system is positioned remote from the chemical to receive at least a portion of the third beam. An adaptive optics system at least partially compensates the light beam degradation caused by atmospheric turbulence. A focusing system is used to bring together the light passed through the chemical; the focusing system includes a multimode fiber for the light collection, The detector system provides information on a phase change in the third beam relative to the second beam that is indicative of at least one of, absorption spectrum and concentration of the chemical.

    Abstract: An image processing system which performs photography of the teeth of a patient while causing a plurality of illumination light LEDs of different wavelengths to emit light by means of a photography device when producing a crown repair or denture of the patient, whereby image data are acquired. The image data are transmitted to a dental filing system constituting a processing device where color reproduction data are determined through computation. In addition, color reproduction data are transmitted to the dental technician's office via a public switched network. A repair material compound ratio calculation database is searched and compound data for a material that matches the hue of the patient's teeth is retrieved, so that a crown repair or denture or the like that very closely matches the color of the patient's teeth can be produced.

    Abstract: An optical arrangement and method of filtering include a beam splitter that accepts an incident beam and transmits light from the incident beam of a first polarization and reflects light from the incident beam of a second polarization. The transmitted light is a first beam and the reflected light is a second beam. A first spectral filter, receives the first beam, reflects a first spectral band of the first beam, and transmits the remainder of the first beam. A second spectral filter receives the remainder of the first beam and reflects a second spectral band of the first beam. The first and second spectral filters can also receive the second beam and reflect similar first and second spectral bands. The spectral bands are then returned to the beam splitter, where they may be directed toward a dispersal element or an array of photodetectors.
