| abstract |
An optical device, a method of detecting the degree of inclination of a three-dimensional object, and a method of detecting a line of sight. The optical device includes a plurality of light emitters configured to irradiate an object with light, a detector configured to detect the light reflected by the object and output a signal based on the light reflected by the object, and circuitry configured to output data of a degree of inclination of the object obtained based on an output signal output from the detector. In the optical device, the light emitted from the light emitter is temporally modulated by a code having orthogonality, and the plurality of light emitters include a first light emitter and a second light emitter. In the optical device, the first light emitter emits the light at a timing different from a timing at which the second light emitter emits the light. |
