Abstract
The present invention provides an asymmetric optical sensor device comprising: a light emitting unit for outputting light; a light receiving unit which receives the light reflected by an external object, and consists of a plurality of pixels which correspond to regions of different angles with respect to the light emitting unit and are arranged in a row; and a lens unit for diffusing the light from the light emitting unit. The light amounts received by the plurality of pixels are light amount values which are asymmetric with respect to the center of the light receiving unit.
Claims20
An asymmetric optical sensor device, comprising:
- a light emitting unit to emit light toward an external object;
- a light receiving unit to receive light reflected by the external object, the light receiving unit including a plurality of pixels arranged in a row to correspond to regions having different angles with respect to the light emitting unit;
- and
- a lens unit to diffuse the light of the light emitting unit,
- wherein amounts of light received by the plurality of pixels have light amount values that are asymmetric with respect to a center axis of the light receiving unit.
An asymmetric optical sensor device comprising:
- a light emitting unit to emit a light;
- a first lens unit to diffuse the light emitted from the light emitting unit and to direct the diffused light toward an area to sense any object in the area;
- a second lens unit to receive a light reflected from the object in the area and to generate a reflected diffused light from the object;
- and
- a light detecting unit to receive the reflected diffused light from the second lens unit,
- wherein a center axis of the first lens unit and a center axis of the light emitting unit are misaligned with respect to each other, or a center axis of the second lens unit and a center axis of the light detecting unit are misaligned with respect to each other.
