Claim Text:
1. A method of configuring an acousto-optic lens for manipulating a beam of electromagnetic radiation so as to be deflected and focused toward a desired location in space, said acousto-optic lens comprising at least a first acousto-optic deflector driven by a first drive frequency and a second acousto-optic deflector driven by a second drive frequency, said method comprising: for each of a plurality of possible locations in space, separately storing data related to a preferred frequency pair, wherein a preferred frequency pair for a first one of said possible locations in space consists of a first preferred drive frequency for said first acousto-optic deflector and a second preferred drive frequency for said second acousto-optic deflector, said preferred frequency pair being such that if said first and second preferred drive frequencies of said pair were applied at the same time to said respective first and second acousto-optic deflectors, said beam of electromagnetic radiation would be deflected toward said first one of said possible locations in space; consulting said data to determine a preferred frequency pair based on said desired location in space; determining first and second drive frequencies as a result of said consulting step.
