METHOD OF SCANNING AN OPTICAL BEAM USING AN ACOUSTO-OPTIC DEFLECTOR DRIVEN BY CHIRPED ACOUSTIC SIGNALS
The object of the invention relates to a method for scanning with an optical beam (50) using a first acousto-optic deflector (15, 15′) having an optical axis along a Z-axis and at least one acousto-optic crystal layer (14), involving directing the optical beam (50) in the first acousto-optic deflect...

| description | The object of the invention relates to a method for scanning with an optical beam (50) using a first acousto-optic deflector (15, 15′) having an optical axis along a Z-axis and at least one acousto-optic crystal layer (14), involving directing the optical beam (50) in the first acousto-optic deflector (15, 15′), and deflecting the optical beam (50) along an X-axis perpendicular to the Z-axis by means of the first acousto-optic deflector (15, 15), during which generating a plurality of acoustic chirp signals (30) in the at least one acousto-optic crystal layer (14) of the acousto-optic deflector (15, 15′) by-generating a first acoustic chirp signal (30a) having a duration of τ in the acousto-optic crystal layer (14), then-generating a second acoustic chirp signal (30b) in the acousto-optic crystal layer (14) within a τ period of time counted from the start of the generation of the first acoustic chirp signal (30a). |
