APPARATUS AND METHOD FOR DETECTING MICROBES OR BACTERIA AND SCATTERING CHAOTIC WAVE IN NAIL PLATES AND TEETH OR GUMS USING LASER SPECKLE PATTERNS

摘要

Disclosed are an apparatus for measuring chaotic wave scattering and microorganisms inside a nail and a mouth, and a method therefor using laser speckle. The apparatus for measuring the microorganisms comprises: a light source radiating light to a sample corresponding to a specific body portion; and a measurement unit measuring laser speckle formed by multiple scattering of the light incident to the specific body portion at a predetermined time interval and measuring whether or not microorganisms exists in the specific body portion based on a pattern change of the laser speckle indicating a change degree in accordance with time of the measured laser speckle.
