Coherent Optical Analog Computer for the Evaluation of Interferograms
Journal of the Optical Society of America, 1971A method for the Fourier transformation of one-dimensional functions, especially interferograms, with coherent light is described. The functions to be transformed are represented in the form of transparent masks with amplitude transmittance T=±1. Negative values of amplitude transmittance are realized with a phase plate.

Optical Analog Feedback in Euglena-Based Neural Network Computing
2012Using living microbial cells in computational processing is a fascinating challenge to incorporate their autonomous adaptation and exploration abilities into a physical computing algorithm [1]. When the stimulus to the cells is given as analog values, more flexible solutions would be expected in microbe-based neurocomputing [1] owing to the diversity ...

Analog computational imaging with meta-optics
Conventional optical information processing systems, particularly those used for real-time image transformation and analysis, face growing limitations in terms of size, speed, energy efficiency, and integration with electronic systems. Traditional optical components lack the flexibility to perform complex processing tasks in a compact format, while ...openaire +5 more sources

Analog computing with optical and microwave bosonic systems
148 pages ; Moore's law continues to push the boundaries of capabilities with today's digital electronics, albeit with a much slower rate than decades prior. The end of Dennard scaling has similarly made digital electronics difficult to continue scaling with energy efficiency.openaire +2 more sources
