Abstract : This patent relates generally to the laser art and, more particularly, to apparatus for scanning an annular shaped light beam emitted by a laser. With the rapid advance in the laser state-of-the-art, it has become possible to have a laser, such as a conventional CO2-N2-He laser, emit or produce an annular shaped light beam. This invention pertains to apparatus for scanning any desired preselected annular portion of an annular shaped light beam and ascertaining the power output of said preselected annular portion.
