Abstract: A light detection and ranging mirror comprises a receiving portion and a transmitting portion offset by an angle about the scan axis relative to a surface plane of the receiving portion. Respective centroids of the receiving and transmitting portions are positioned at a common point on the scan axis while the receiving and transmitting portions rotate around the scan axis. The transmitting portion is positioned to reflect a light pulse onto a target as a transmitted spot. The receiving portion is positioned to direct the light pulse reflected from the target onto the receiving portion as a receiving portion field-of-view. The receiving portion field-of-view overlaps the transmitted spot as a function of a range of the target.

Abstract: A method for determining a range to a target comprises rotating a mirror unit around a scan axis. A light pulse is reflected off of a transmitting portion of the mirror unit toward the target. A light pulse, received from the target, is reflected off of a receiving portion of the mirror unit toward a receiver. The method includes compensating for a lag angle, caused by the rotation of the mirror unit around the axis, between the time the light pulse is reflected from the transmitting portion and the time the received light pulse is reflected from the receiving portion. The compensation includes angularly offsetting the transmitting portion about the scan axis from a surface plane of the receiving portion.

Abstract: A light detection and ranging system includes a mirror unit rotating around a scan axis. The mirror unit includes a receiving portion and a transmitting portion offset by an angle about the scan axis relative to a surface plane of the receiving portion. Respective centroids of the receiving and transmitting portions are positioned at a common point on the scan axis while the receiving and transmitting portions rotate around the scan axis. A transmitter transmits a light pulse toward the mirror unit. The transmitting portion is positioned to reflect the light pulse toward a target. A receiver is positioned to reflect the light pulse reflected from the target toward the receiver. The angle offset compensates for a change between a cone of illumination of the transmitting portion and a field-of-view of the receiving portion resulting from the rotation of the mirror unit.
