Latest Patents

Sawanobori is named on a patent titled “Mirror unit, distance measurement device and laser radar, and mobile body and fixed object having the mirror unit and the distance measurement device or the laser radar.” The invention describes a rotating mirror unit with multiple pairs of first and second reflecting surfaces, each inclined relative to the rotation axis and oriented in crossing directions. A light beam reflects first from one surface and then from its paired surface, scanning an object as the mirror rotates. The reflecting surfaces are formed on separate members that can be combined to select the beam’s emission angle. The patent describes applications in distance-measurement devices, laser radar, mobile bodies, and fixed objects.
