Claim Text:
1. An apparatus comprising: a first optical fiber operative for receiving a first light signal at a first input facet and providing a second light signal at a first output facet, the first optical fiber supporting a first plurality of optical modes that collectively define the second light signal; a first spatial light modulator, the first spatial light modulator being operative for providing the first light signal to the first input facet and controlling at least one of the relative phase and relative amplitude of each of the first plurality of optical modes to control the shape of the second light signal and direct the second light signal to at least one of a plurality of object points within a scan region; a second spatial light modulator, the second spatial light modulator being operative for receiving a third light signal from the first input facet and providing a fourth light signal, wherein the third light signal comprises light reflected from the scan region into the first output facet, and wherein the second spatial light modulator is operative for manipulating the phase configuration of the third light signal to selectively pass light from one of the plurality of object points to a power monitor; and a first sensor located within the scan region, wherein the first sensor provides a first sensor signal when the second light signal is incident on it.
