The General Quantum Limit for and the Optimization of the Minimum Measurable Frequency Shift in a Laser
Selim M. Shahriar, Ruoxi Zhu, Jinyang Li +1
We show that, contrary to conventional understanding, the minimum measurable frequency shift (MMFS) for a single-mode ideal laser is determined by a combination of phase diffusion…
Opto-Atomic Spatio-Temporal Holographic Correlators for High-Speed 3D CNNs
Xi Shen, Bowen Qi, Tabassom Hamidfar +1
Three-dimensional convolutional neural networks (3D CNNs) have demonstrated remarkable performance in video recognition tasks by processing both spatial and temporal features. Howe…
Slow Light Augmented Fabry-Perot Cavity for Enhanced Sensitivity in Measuring Frequency Shift
Ruoxi Zhu, Zifan Zhou, Dustin Greenwood +3
Recently, it has been shown that a slow-light augmented unbalanced Mach-Zehnder interferometer (SLAUMZI) can be used to enhance significantly the sensitivity of measuring the frequ…
Shift, Scale and Rotation Invariant Multiple Object Detection using Balanced Joint Transform Correlator
Xi Shen, Julian Gamboa, Tabassom Hamidfar +2
The Polar Mellin Transform (PMT) is a well-known technique that converts images into shift, scale and rotation invariant signatures for object detection using opto-electronic corre…
Automatic Event Recognition Employing Optically Excited Electro-Nuclear Spin Coherence
Shamima Mitu, Xi Shen, Julian Gamboa +2
An analog automatic event recognition (AER) system can be realized by combining the technique of holographic image recognition with the process of temporal signal correlation emplo…
Debiased Opto-electronic Joint Transform Correlator for Enhanced Real-Time Pattern Recognition
Julian Gamboa, Xi Shen, Tabassom Hamidfar +2
Opto-electronic joint transform correlators (OJTCs) use a focal plane array (FPA) to detect the joint power spectrum (JPS) of two input images, projecting it onto a spatial light m…
