Abstract:
1. A laser scanning system comprising: a laser source operable for transmitting a laser beam having a generally circular cross section and measurable diameter thereof, the laser beam transmitted along a beam axis; a first scanner having a first mirror operable thereby for at least one of oscillations and rotations, the first mirror positioned for receiving the generally circular laser beam reflecting the laser beam therefrom, wherein the first mirror is angled with respect to the beam axis providing an angle of incidence such that the generally circular laser beam received thereby and scanned within an oval shaped beam area, and wherein the first mirror has a trapezoidal shape including a length dimension measured along an axis of rotation of the first mirror equal to at least one diameter of the laser beam incident on the first mirror, a bottom width dimension measured orthogonal to the axis of rotation greater than a top width dimension and a width dimension therebetween equal to at least a secant of the angle of incidence of the laser beam onto the first mirror times the diameter thereof; a second scanner having a second mirror operable thereby for at least one of oscillations and rotations, the second mirror positioned for receiving the laser beam reflected from the first mirror and reflecting the laser beam therefrom, the first mirror positioned proximate the second mirror; and a target positioned for receiving the laser beam reflected from the second mirror.
