Latest Patents

Yuki Ashida's latest patents include a MEMs phased-array for LiDAR applications. This invention describes an optical scanner that incorporates micro-electromechanical system phased-arrays suitable for use in a LiDAR system. The scanner features an optical transmitter with first phased-arrays that receive light from a light source, forming a swath of illumination in a far-field scene. It modulates the phases of the light to sweep or steer the swath over the scene in two dimensions. Additionally, the optical receiver in the scanner includes second phased-arrays that receive light from the far-field scene and direct some of the light onto a detector. These second phased-arrays are designed to de-scan the received light, directing light reflected from the far-field scene onto the detector while rejecting background light. In one embodiment, the second phased-arrays direct light from a slice of the far-field scene onto a one-dimensional detector array.

Another notable patent is the light irradiation apparatus, drawing apparatus, and phase difference generator. In this invention, laser light from a light source is guided to an irradiation plane by an irradiation optical system. The system features element lenses that are arrayed, allowing light fluxes that have passed through the element lenses to enter transparent elements. The irradiation regions of the light from the element lenses are superimposed on the irradiation plane. The optical path lengths of three transparent elements corresponding to three target element lenses are determined to ensure that the peak position of light intensity on the irradiation plane resulting from the interference between the light fluxes through one target element lens pair differs from that of the other pair. This design effectively suppresses variations in light intensity caused by interference between the light fluxes on the irradiation plane.
