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: Colorimeter includes an illumination light reception unit, an attached part, a detection unit, a recognition unit, a color measurement control unit, and an output unit. To the attached part, a mask member is attached to cover the illumination light reception unit. The detection unit detects parts disposed on the mask member. The recognition unit recognizes information on the kind of the mask member in accordance with a detection result by the detection unit. The color measurement control unit causes the recognition unit to recognize information on the kind of mask member in accordance with the detection result at a first timing, and on the kind of mask member in accordance with the detection result at a second timing. The output unit performs a predetermined output in response to a discordance between the information on the kind of mask member at the first timing and at the second timing.

Abstract: A handheld LIBS spectrometer system features an optics stage moveable with respect to a housing and including a laser focusing lens. A laser source is mounted in the housing for directing a laser beam to a sample via the laser focusing lens. A detection fiber is mounted in the housing and is fixed relative thereto. A first mirror is fixed relative to the housing and includes an aperture for the laser beam. This mirror is oriented to re-direct plasma radiation for delivery to the detection fiber. A controller subsystem is responsive to the output of a spectrometer subsystem and is configured to control the laser source and the optics stage.
