Amplitude-smoothed BPOF and amplitude-smoothed amplitude-encoded BPOF

SPIE Proceedings, 1990
In this paper smoothed binary phaseonly filtcr(ASBPOF) and amplitude smoothed amplitude encoded BPOF(ASAEBPOF) are presented. By computer simulation in the case of symmetrical and unsymmetrical characters it is concluded that with the BPOF and AEBPOF these filters sacrifice light efficiency due to the amplitudesmoothed factor it yield much better ...

Amplitude-only versus amplitude-phase estimation

IEEE Transactions on Instrumentation and Measurement, 1990
The feasibility of transfer function estimation based on amplitude-only measurements is investigated, and this method is compared with the amplitude-phase (full complex spectrum) method. It is shown that the amplitude-only-based method is a feasible alternative to the full complex spectrum method when the minimum in-phase transfer function of the ...

Probabilistic Amplitude Shaping

Foundations and Trends® in Communications and Information Theory, 2023
Summary: Probabilistic amplitude shaping (PAS) proposed in [\textit{G. Böcherer} et al., ``Bandwidth efficient and rate-matched low-density parity-check coded modulation'', IEEE Trans. Commun. 63, No. 12, 4651--4665 (2015; \url{doi:10.1109/TCOMM.2015.2494016})] is a practical architecture for combining non-uniform distributions on higher-order ...

High Efficiency Metasurfaces with Independent Control of Phase, Amplitude, and Polarization

IEEE Asia-Pacific Conference on Antennas and Propagation, 2018
Metasurfaces that can simultaneously manipulate amplitude and phase have attracted great attention and have great application prospects due to their powerful beam steering capabilities.

Amplitude-modulated interferometry

Optics Letters, 1990
Specific modulating procedures of the interfering amplitudes in a double-beam interferometer lead to highprecision measurements and insensitivity to changes in reflectivity. The performance of such an interferometer is superior to that of a phase-shifting interferometer because the modulated quantity is the amplitude rather than the phase, which is the
