Optical scanning is a prevalent technique for optical neural interfaces wherelight delivery with high spatial and temporal precision is desired. However,due to the sequential nature of point-scanning techniques, the settling time ofoptical modulators is a major bottleneck for throughput and limitsrandom-access targeting capabilities. While fast lateral scanners exist,commercially available varifocal elements are constrained to >3ms settlingtimes, limiting the speed of the overall system to hundreds of Hz. Fasterfocusing methods exist but cannot combine fast operation and dwellingcapability with electrical and optical efficiency. Here, we present a varifocalmirror comprised of an array of piston-motion MEMS micromirrors and a customdriver ASIC, offering fast operation with dwelling capability while maintaininghigh diffraction efficiency. The ASIC features a reconfigurable nonlinear DACto simultaneously compensate for the built-in nonlinearity of electrostaticactuators and the global process variations in MEMS mirrors. Experimentalresults demonstrate a wide continuous sweeping range that spans 22 distinctlyresolvable depth planes with refresh rates greater than 12 kHz.
