Latest Patents

Gillis's latest patents include groundbreaking work on recording and reading synthetic holograms. This invention involves recording a byte of binary data as a synthetic Fourier transform hologram. A time-varying control signal is utilized to intensity modulate a coherent light beam, which scans across a photosensitive recording film. The amplitudes of different spatial frequencies in the data band are adjusted to compensate for signal-to-noise roll-off, ensuring high-quality data retrieval. During the readout process, an inverse Fourier transformation is performed optically to produce the original byte of data, which is then converted into an electrical data signal.

Another significant patent by Gillis is the Fourier transform generator for bi-level samples. This apparatus computes the Fourier coefficients of a finite block of bi-level bits by formatting the bits into an even function symmetrical about an origin. This innovative approach allows for the computation of a Fourier transform that results in only cosine terms, simplifying the process and enhancing efficiency.
