Abstract: Provided is an optical source apparatus that may generate two different optical frequency combs. The optical source apparatus includes an optical resonator and a continuous wave laser emitting laser light having a spectrum component corresponding to a resonance frequency of the optical resonator, and the optical resonator is configured to generate a first frequency comb and a second frequency comb having different modes by interacting with the laser light emitted by the continuous wave laser.

Abstract: Physiological parameter detecting apparatuses and methods of detecting the physiological parameters are provided. A physiological parameter detecting apparatus includes: a light source configured to emit a light onto a region of an object; an optical path converter configured to receive the light returning from the object and convert an optical path of the received light; an optical detector configured to detect the light that has the converted optical path; and a controller configured to extract physiological information of the object from the detected light.

Abstract: A method for measuring blood constituents is provided. The method includes radiating an area of a subject's body, containing blood constituents and dynamic and static tissue components, with at least two light beams, detecting at least one backscattered light feedback from blood constituents and dynamic and static tissue components, the feedback representing at least one interferometric signal from each of the at least two light sources, filtering the at least one interferometric signals in accordance with a frequency band which contains frequencies of interferometric oscillations, defining dynamics of blood constituents, performing analog-to-digital (AD) conversion of the filtered signals at a frequency corresponding to the frequency band, to form discrete filtered signals, obtaining from the discrete filtered signals, a set of spectral-time features of signals, and obtaining concentration of the blood constituents based on functional relationships of the obtained set of spectral-time features of signals and concentrations of the blood constituents.

Abstract: A biometrics authentication apparatus and a biometrics authentication method are disclosed. The biometrics authentication apparatus includes: a light source configured to emit a light; a modulator configured to change a spatial distribution of the light that is scattered and reflected from a region of interest of a user; a detector configured to detect an integral power of the light that is scattered from the region of interest; and a processor configured to obtain a measurement signal based on the integral power of the light, compare the measurement signal with a reference signal stored in a memory, and determine whether to authenticate the user based on a degree of match between the measurement signal and the reference signal.
