摘要： An optical device includes a light source that emits light to irradiate an object, a light emission driver that drives the light source to emit light at a predetermined light emission period, a position detector that outputs a detection signal corresponding to reflected light that is the light reflected by the object, and a signal extractor that extracts, from the detection signal, a signal with a period corresponding to the light emission period by using a reference signal with a period corresponding to the light emission period, and outputs the extracted signal.

摘要： A retinal projection display device for projection of an image onto a retina of a wearer wearing an eyeglass-type support is provided. The retinal projection display device includes the eyeglass-type support including a temple; a light source; an optical scanner disposed in the temple and configured to scan light from the light source so as to form the image; a projector configured to project the image formed by the optical scanner onto the retina; an optical deflector disposed in the temple and configured to change a projection direction of the image formed by the optical scanner; and a translation member configured to translate the optical scanner and the optical deflector in a direction in which the temple extends.

摘要： 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.

摘要： A displacement measurement device includes: an irradiation unit that irradiates a measurement object with coherent light; a luminance-change coordinate point detection unit that detects a luminance-change coordinate point where a luminance change has occurred, based on light reflected from the measurement object, and outputs data related to the luminance-change coordinate point; and circuitry that calculates an amount of displacement of the measurement object, based on the data related to the luminance-change coordinate point, by performing computations of a first numerical sequence and a second numerical sequence. The first numerical sequence includes a set of first elements each representing a location of the luminance-change coordinate point extracted from the data. The second numerical-sequence includes a set of second elements each representing a location of the luminance-change coordinate point extracted from the data.
