摘要： Methods and systems for detecting early stage dental caries and decays are provided. In particular, in an embodiment, laser-induced autofluorescence (AF) from multiple excitation wavelengths is obtained and analyzed. Endogenous fluorophores residing in the enamel naturally fluoresce when illuminated by wavelengths ranging from ultraviolet into the visible spectrum. The relative intensities of the AF emission changes between different excitation wavelengths when the enamel changes from healthy to demineralized. By taking a ratio of AF emission spectra integrals between different excitation wavelengths, a standard is created wherein changes in AF ratios within a tooth are quantified and serve as indicators of early stage enamel demineralization. The techniques described herein may be used in conjunction with a scanning fiber endoscope (SFE) to provide a reliable, safe and low-cost means for identifying dental caries or decays.

摘要： A tool for positioning a scanning device provided with a spectrometer comprises a support having a resting zone suitable for being rested onto a surface, a fixing arrangement for fixing the scanning device to the tool. The support is so dimensioned as to leave uncovered an operative zone in which the spectrometer is movable for acquiring an image provided on a substrate, so that the spectrometer can acquire the image while the support is resting directly on the substrate. The tool further comprises a vision device comprising a video camera for recording the image and a control unit that controls the video camera, the control unit being programmed to recognise pre-established points of the image recorded by the video camera.

摘要： The present invention provides an interferometer and the like, that is capable of ensuring the speed stability of the movable mirror while achieving the speed up of the reciprocal movement of the moving mirror and suppressing the increment of the maximum instantaneous thrust force required for the turning back as much as possible. The interferometer includes a moving mirror, a movement mechanism for reciprocating the moving mirror, a movement control part for controlling the movement mechanism and allowing the moving mirror to be reciprocated at a constant speed, and a measurement part for measuring a position of the moving mirror. The movement control part is adapted to receive target position data indicating a target position of the moving mirror, and control the movement mechanism to bring the measurement position of the moving mirror measured by the measurement part close to the target position indicated by the target position data.
