Abstract
A snowplow laser guidance system is disclosed. The system can include, for example, a laser light source, a laser exit window through which a laser beam generated by the laser light source is transmitted, and a pressurized gas conduit. The pressurized gas conduit can have an opening positioned such that gas released through the opening flows across a face of the laser exit window. This can be useful to remove accumulated material, such as snow, ice, water, and dirt. The gas can be, for example, pressurized gas from a pressurized gas source of a snowplow vehicle. Release of pressurized gas across the face of the laser exit window can occur at a programmed frequency and/or in response to an operator signal, such as a signal from a switch on a control panel. The system also can include a heater connected to the laser exit window for defrosting.
