Combined with fast imaging and modulation transfer function conversion that may be externally implemented in several ways, multiple hexapod micro-robots can optimize MTF of optical-train elements simultaneously. This active alignment approach relies on the ability of multiple optimization processes to be defined and run on hexapods carrying each element in the lens assembly. This can vastly improve process throughput for final assembly and qualification of precision optical imaging devices. Optimization can even be performed during adhesive curing to rectify curing stresses and improve device quality.
Combined with fast external optical power metrology, hexapod micro-robots can optimize optical throughput through optical trains, laser cavities, and photonic assemblies, across multiple degrees of freedom and multiple channels, all in one step. Compared to traditional techniques that until now have necessitated repetitive, looping sequences of positional tweaking across the involved degrees-of-freedom, the resulting throughput improvement can exceed two orders of magnitude. This can virtually eliminate the alignment process as a contributor to manufacturing process cycle time.
