Patent ID: 8456725

Claim:
A method comprising: projecting a collimated light beam from an optical system to a plane during a first mode of operation of said optical system; and projecting a convergent light beam from said optical system to said plane during a second mode of operation of said optical system, wherein said projecting said collimated light beam comprises: routing a first light bundle from a light source to an orthogonal pair of galvanometer scanning mirrors; and controlling said orthogonal pair of galvanometer scanning mirrors to: (a) direct said first light bundle to a first light path in said optical system along which said first light bundle propagates to produce said collimated light beam; and (b) control a trajectory of said first light bundle in said first light path to steer said collimated light beam through said plane at a designated incidence angle, and wherein said projecting said convergent light beam comprises: routing a second light bundle from said light source to said orthogonal pair of galvanometer scanning mirrors; and controlling said orthogonal pair of galvanometer scanning mirrors to: (a) direct said second light bundle to a second light path in said optical system along which said second light bundle propagates to produce said convergent light beam; and (b) control a trajectory of said second light bundle in said second light path to steer said convergent light beam to a target position in said plane.
