Abstract: The present invention belongs to the field of optical technology, disclosing a quadrilateral common-path time-modulated interferometric spectral imaging device and method. The present invention sets up a moving mirror scanning mechanism in a quadrilateral common path interferometer for generating optical path differences that vary with time, so that the quadrilateral common-path time-modulated interferometric spectral imaging device operates in the staring observation mode. The invention can make the quadrilateral common-path time-modulated interferometric spectral imaging device not only retain the advantages of common optical path spectroscopic technology, but also obtain high spectral resolution.

Abstract: 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.

Abstract: 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.
