OPTICAL SYSTEM THAT SELECTIVELY PROVIDES EITHER OF A COLLIMATED LIGHT BEAM OR A CONVERGENT LIGHT BEAM

摘要

A system comprising: a first optical subsystem; a second optical subsystem; and an orthogonal pair of galvanometer scanning mirrors that: (i) during a first mode of operation: (a) receives a first light bundle from a light source; (b) directs the first light bundle to a first light path in the first optical subsystem; and (c) controls a trajectory of the first light bundle in the first light path to steer the first light bundle through a plane at a designated incidence angle; and (ii) during a second mode of operation: (a) receives a second light bundle from the light source; (b) directs the second light bundle to a second light path in the second optical subsystem; and (c) controls a trajectory of the second light bundle in the second light path to steer the second light bundle to a target position in the plane, wherein the first optical subsystem transforms the first light bundle so that the first light bundle is projected to the plane in a collimated light beam; and wherein the second optical subsystem transforms the second light bundle so that the second light bundle is projected to the plane in a convergent light beam.
