On-Chip CMOS Threshold Processing
This technology is a method of processing the interference fringes produced by the UA19-178 system. It employs a threshold-type operation at the incoherent light level so that only constructive interference is recorded, which greatly speeds up the data processing by reducing the amount of data to process in the first place. Processing occurs on the...
