Abstract
An information processing apparatus includes: a light emitting unit configured to emit light; an optical unit configured to induce an optical influence to the light from the light emitting unit, the optical unit having an astigmatic lens configured to generate astigmatism with a plurality of focal lengths; a detecting unit configured to detect the light emitted in the light emitting unit, radiated outside through the optical unit, and reflected by an object; and a measuring unit configured to measure a distance to the object based on astigmatism generated in the reflection light detected in the detecting unit.
Claims20
A distance measurement system, comprising:
- a light source configured to emit emission light;
- an optical unit having an aberration property and a plurality of focal lengths, wherein the emission light is configured to be emitted through the optical unit to an object;
- a detecting unit configured to detect reflection light reflected by the object;
- and
- a processor configured to calculate a distance between the distance measurement system and the object based on the aberration property in the reflection light.
A distance measurement system, comprising:
- a light source;
- an astigmatic lens having an aberration property and a plurality of focal lengths, wherein light emitted by the light source is passed by the astigmatic lens to an object;
- an image sensor configured to detect reflection light reflected by the object;
- and
- a processor configured to calculate a distance between the distance measurement system and the object based on the aberration property in the reflection light.
