Abstract: A system and method for scanning of coherent LIDAR. The system includes a motor, a laser source configured to generate an optical beam, and a deflector. A first facet of the plurality of facets has a facet normal direction. The deflector is coupled to the motor and is configured to rotate about a rotation axis to deflect the optical beam from the laser source. The laser source is configured to direct the optical beam such that the optical beam is incident on the deflector at a first incident angle in a first plane, wherein the first plane includes the rotation axis, wherein the first incident angle is spaced apart from the facet normal direction for the first facet. A second facet of the plurality of facets includes an optical element configured to deflect the optical beam at the first incident angle into a deflected angle.

Abstract: A laser beam (L50) is reflected by a light beam scanning device (60) and irradiated onto a hologram recording medium (45). On the hologram recording medium (45), an image (35) of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin (B). The light beam scanning device (60) bends the laser beam (L50) at the scanning origin (B) and irradiates the laser beam onto the hologram recording medium (45). At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam (L60) on the hologram recording medium (45) is changed with time. Diffracted light (L45) from the hologram recording medium (45) produces a reproduction image (35) of the linear scatter body on a light receiving surface (R) of the stage 210.

Abstract: Product and/or item customization based on physiological data is described. One or more sensors worn by a person or a group of people and/or attached with one or more items may generate sensor data. Data characterizing one or more physiological attributes of the person or group may be determined based at least in part on the generated sensor data. Item customization may include a customized design. For example, the customized design may include one or more personalized graphics generated based on the physiological data, and/or one or more customized item components with parameters set based on the physiological data. The customized design may be provided to an item customization facility for presentation, assembly and/or manufacture. Item customization may further include selecting for consideration a set of matching items based at least in part on the physiological data.
