Abstract
A laser scanner apparatus with an electromagnetic radiation source configured to transmit a laser beam having a beam path. A cylindrical element is provided with an electromagnetically reflective surface. The laser source is configured so the beam is incident on the reflective surface at a predetermined incident angle. The cylindrical element is configured to be driven to rotate at a predetermined rotation rate about an offset longitudinal axis whereby the beam path of the incident beam is varied so as to scan a scene of interest.
Claims5
A laser scanner apparatus comprising:
- an electromagnetic radiation source configured to transmit a beam having a beam path,
- a cylindrical element comprising an electromagnetically reflective surface,
- the source configured whereby the beam is incident on the reflective surface at a predetermined incident angle, and,
- the cylindrical element configured to rotate at a predetermined rotation rate about an offset longitudinal axis whereby the beam path is varied.
A method for scanning a scene of interest with an electromagnetic beam comprising the steps of:
- rotating a cylinder comprising an electromagnetically reflective surface about an offset longitudinal axis of rotation, and,
- imaging an electromagnetic beam on the reflective surface whereby an angle of incidence of the beam on the reflective surface is varied dependent on a rotation position of the cylinder whereby the beam is scanned across the scene of interest.
