US Patent 10891749 Depth mapping

A device for depth mapping of an object comprises an emitter comprising a laser and an optical component, an actuator and a control processor unit. The actuator is arranged to change the relative position and/or relative orientation of the optical component to the laser. The control processor unit is configured to receive information relating to change in the location and/or orientation of the device during use of the device, and to instruct the actuator to change the relative position and/or relative orientation of the optical component to the laser so as to compensate for change in the location and/or orientation of the device during use of the device.
