Title:
DEVICE FOR IDENTIFYING LIGHT EMITTING BODY OR ORGANIZED BODY IN MOUTH, AND DEVICE FOR INSPECTING ORGANIZED BODY IN MOUTH
Document Type and Number:
WIPO Patent Application WO/2022/269877
Kind Code:
A1
Abstract:
The present invention uses a light source (non-polarized light, linearly polarized light, circular polarized light) that has low energy (360-970 nm) not causing health damage and has a half width of 60 nm or less. Light source light from the light source is applied to an organized body including a healthy tooth, decayed tooth, demineralized state, decayed tooth, microcrack, microvoid, dental calculus, dental plaque, and gum in a mouth. The intensity distribution of the light emission, Rayleigh scattering light, Mie scattering light, or Raman scattering light from the organized body in a mouth is selectively highlighted and imaged with a color camera module that includes a CMOS sensor and a lens without being equipped with an IRCF and that is optionally equipped with a longpass filter, notch filter, linearly polarized light filter, and circular polarized light filter. The highlighted intensity distribution image is taken out to the external as an RGB signal. The present invention can provide measures against contamination derived from an organized body in a mouth. The health condition of an organized body in a mouth and a lesion therein as well as a part which is at high risk of becoming a lesion from the viewpoint of prevention medicine are optically evaluated with high accuracy in a non-invasive manner thereby.
