摘      要：Digital light projector systems are crucial components in applications,including computational imaging,fluorescence microscopy,and highly parallel data *** technology based on digital micromirror displays are limited to absolute frame rates in the few tens of kiloframes per second and require the use of external light sources and coupling ***,to realize gray-scale pixel values using duty cycle control,frame rates are reduced proportionally to the number of gray levels *** we present a self-emissive chip-scale projector system based on micro-LED pixels directly bonded to a smart pixel CMOS drive *** 128×128 pixel array can project binary patterns at up to 0.5 Mfps and toggle between two stored frames at megahertz *** projector has a 5-bit gray-scale resolution that can be updated at up to 83 kfps,and can be held in memory as a constant bias for the binary pattern ***,the projector can be operated in a pulsed mode,with individual pixels emitting pulses down to a few nanoseconds in ***,this mode can be used in conjunction with the high-speed spatial pattern *** a demonstration of the data throughput achievable with this system,we present an optical camera communications application,exhibiting data rates of5 Gb/s.
