摘要： Provided are a Raman probe and a bio-component analyzing apparatus using the same. The Raman probe according to an embodiment of the present disclosure may include: a probe head having a concave part configured to receive skin of an object being inserted into the concave part when the probe head comes into contact with the skin of the object; a light source part configured to emit light onto the skin inserted into the concave part; and a light collector formed above the concave part and configured to collect Raman scattered light from the skin inserted into the concave part. The light source part may be disposed on a side of at least one of the light collector and the concave part.

摘要： A spectroscopic apparatus and method for analyzing a biological material are provided. The spectroscopic apparatus may analyze a biological material which has an internal non-uniform tissue depending on a position thereof. The apparatus may include at least one detector configured to obtain respective detection spectrums corresponding to a plurality of measurement regions that are at mutually different positions of the biological material, and an information processor to determine whether the measurement regions are normal by mutually comparing the detection spectrums, or converting contribution degrees of data for a specific component of the biological material by differentiating the detection spectrums.

摘要： An optical apparatus for non-invasively measuring a bio-signal is provided. The optical apparatus may include an interface housing including: a guide part defined by an interior space of the interface housing and configured to guide an object to a measurement position; and a pressurizing part configured to induce congestion of a second portion of the object by pressing a first portion of the object when the object is disposed within the guide part; and a measurer including: a light source provided on an upper side of the interface housing and configured to emit light to the second portion of the object when the object is at the measurement position; and a detector configured to measure a bio-signal from the second portion by detecting light scattered or reflected from the second portion.
