Abstract
A spectrometer includes: a dispersive element configured to split light; a detector comprising a plurality of pixels configured to receive the split light; an optical mask disposed in an optical path of the light between the dispersive element and the detector and comprising a plurality of light transmitting portions and a plurality of light blocking portions which are arranged alternately; and a driver configured to control a position of the optical mask or a position of the detector, and change a light incident area of each of the plurality of pixels to receive the light incident on the plurality of light transmitting portions of the optical mask.
Claims20
A spectrometer comprising:
- a dispersive element configured to split light;
- a detector comprising a plurality of pixels configured to receive the split light;
- an optical mask disposed in an optical path of the light between the dispersive element and the detector and comprising a plurality of light transmitting portions and a plurality of light blocking portions which are arranged alternately;
- and
- a driver configured to control a position of the optical mask or a position of the detector, and change a light incident area of each of the plurality of pixels to receive the light incident on the plurality of light transmitting portions of the optical mask.
An apparatus for estimating bio-information, the apparatus comprising:
- a light source configured to emit light;
- a dispersive element configured to split the light;
- a detector comprising a plurality of pixels configured to receive the split light;
- an optical mask disposed in an optical path of the light between the dispersive element and the detector, and comprising a plurality of light transmitting portions and a plurality of light blocking portions which are arranged alternately;
- a driver configured to control a position of the optical mask or a position of the detector, and change a light incident area of each of the plurality of pixels to receive the light incident on the plurality of light transmitting portions of the optical mask;
- and
- a processor configured to estimate bio-information of a user based on a light receiving result of the detector.
An electronic device comprising:
- a light source configured to emit light;
- a dispersive element provided between the light source and the light detector, and configured to split the light into the light of multiple wavelengths;
- a light detector comprising at least one pixel configured to detect the light emitted from the light source;
- an optical mask that is provided between the light source and the light detector along an optical path of the light, and that comprises a light transmitting portion and a light blocking portion;
- and
- a driver configured to adjust a relative position of the optical mask relative to the light detector, so that a portion of the at least one pixel is aligned with the light transmitting portion of the optical mask, and another portion of the at least one pixel is aligned with the light blocking portion of the optical mask.
