Abstract
An apparatus for acquiring bio-information includes a light source configured to radiate a laser beam to a region of interest including a blood vessel; a sensor configured to sense, from the region of interest, a change of a laser speckle generated by the radiated laser beam; and a controller configured to obtain a bio-signal indicating a change in a blood flow in the blood vessel based on the sensed change of the laser speckle.
Claims22
An apparatus for acquiring bio-information, the apparatus comprising:
- a light source configured to radiate a laser beam to a region of interest including a blood vessel;
- a sensor configured to sense, from the region of interest, a change of a laser speckle generated by the radiated laser beam;
- and
- a controller configured to obtain a bio-signal indicating a change in a blood flow in the blood vessel based on the sensed change of the laser speckle.
A method of acquiring bio-information, the method comprising:
- radiating a laser beam to a region of interest (ROI) including a blood vessel;
- sensing a change of a laser speckle generated by the radiated laser beam, from the region of interest;
- and
- obtaining a bio-signal indicating a change in a blood flow in the blood vessel based on the sensed change of the laser speckle.
An apparatus for obtaining bio-information, the apparatus comprising:
- an optical sensor configured to capture an image of a skin surface of a subject within a region of interest (ROI) and generate data on a portion of the image that has a relative change of a light intensity in relation to a remaining portion of the image;
- and
- a controller configured to obtain the bio-information indicating a change in a blood vessel within the ROI based on the generated data.
