Claim 0:
1. A method of forming a virtual optical marking on a surface, the method comprising:
providing an optical projection device comprising:
a housing;
a linear array of light emitting diodes supported by the housing, the linear array of light emitting diodes defining an array axis intersecting each light emitting diode;
at least one optical component supported by the housing, the at least one optical component being configured to focus light emitted from the linear array of light emitting diodes and generate a linear image having an image axis parallel to the array axis; and

supporting the housing relative to the surface such that the linear image is formed on the surface, thereby virtually marking the surface with the linear image; and
controlling the optical projection device to generate the linear image in response to a signal received by a sensor.
