It had been implemented in the year 2000 and reported based on modified Joint Fourier Transform Correlator ( JTC ) and Bacteriorhodopsin ( BR ) as a holographic optical memory.

The output of both digital and analog correlator can be used to computationally synthesize the interferometer aperture in the same way as with direct detection interferometers ( see above ).
43.
Fine Time Aiding enables a more aggressive search and is claimed to be equivalent to 6 dB more sensitivity than can be achieved by any GPS hardware correlator in the terminal.

Sets of 1.28 MHz coarse frequency channels are transmitted via an optical fibre connection to the correlator subsystem, located in the CSIRO Data Processing Facility near the MWA site.
45.
This technique may be applied in many mathematics-related subjects, for example, in the classical, 2-dimensional computation of the dimer-dimer correlator function in statistical mechanics.
46.
The array also had a new correlator and new, cooled receivers, and some of the microwave links between the telescopes were improved so that the array could observe both hands of polarization.
47.
A major advantage of intensity interferometers is that only the measured intensity observed by each detector must be sent to the central correlator facility, rather than the amplitude and phase of the signal.
48.
While the resulting amount of light was so weak that very long exposure times had to be used, a workable optical correlator was assembled in time to be used when appropriate data became available.

RAL worked hand in hand with the SETI Institute during design and prototyping and was the primary designer of the feed, antenna surfaces, beamforming, correlator, and imaging system for radio astronomy observations.
50.
The correlator subsystem comprises Poly-phase Filter Bank ( PFB ) boards that convert the 1.28 MHz coarse frequency channels into channels with 10 kHz frequency resolution in preparation for cross-correlation.
