Single-exposure height-recovery structured illumination microscopy based on deep learning.

Optics letters
Modulation-based structured illumination microscopy (SIM) is performed to reconstruct three-dimensional (3D) surface topography. Generally speaking, modulation decoding algorithms mainly include a phase-shift (PS) method and frequency analysis techni...

Efficient optical reservoir computing for parallel data processing.

Optics letters
We propose and experimentally demonstrate an optical reservoir computing system in free space, using second-harmonic generation for nonlinear kernel functions and a scattering medium to enhance reservoir nodes interconnection. We test it for one-step...

Hyperspectral image super-resolution based on the transfer of both spectra and multi-level features.

Optics letters
Existing hyperspectral image (HSI) super-resolution methods fusing a high-resolution RGB image (HR-RGB) and a low-resolution HSI (LR-HSI) always rely on spatial degradation and handcrafted priors, which hinders their practicality. To address these pr...

3D medical images security via light-field imaging.

Optics letters
This Letter proposes a selective encryption scheme for three-dimensional (3D) medical images using light-field imaging and two-dimensional (2D) Moore cellular automata (MCA). We first utilize convolutional neural networks (CNNs) to obtain the salienc...

Mitigating the ambiguity problem in the CNN-based wavefront correction.

Optics letters
In this work, we propose an attention-based adaptive optics method that uses a non-local block to integrate phase diversity with a convolutional neural network (CNN). The simulation results showcase the effectiveness of the proposed method to mitigat...

Long short-term memory neural network for directly inverse design of nanofin metasurface.

Optics letters
In this Letter, the neural network long short-term memory (LSTM) is used to quickly and accurately predict the polarization sensitivity of a nanofin metasurface. In the forward prediction, we construct a deep neural network (DNN) with the same struct...

Weighted sampling-adaptive single-pixel sensing.

Optics letters
The novel single-pixel sensing technique that uses an end-to-end neural network for joint optimization achieves high-level semantic sensing, which is effective but computation-consuming for varied sampling rates. In this Letter, we report a weighted ...

Attention-based neural network for polarimetric image denoising.

Optics letters
In this Letter, we propose an attention-based neural network specially designed for the challenging task of polarimetric image denoising. In particular, the channel attention mechanism is used to effectively extract the features underlying the polari...

Rapid ellipsometric determination and mapping of alloy stoichiometry with a neural network.

Optics letters
Due to their tunable physical and chemical properties, alloys are of fundamental importance in material science. The determination of stoichiometry is crucial for alloy engineering. Classical characterization tools such as energy-dispersive x-ray spe...

Deep learning adapted acceleration for limited-view photoacoustic image reconstruction.

Optics letters
The limited-view issue can cause a low-quality image in photoacoustic (PA) computed tomography due to the limitation of geometric condition. The model-based method is used to resolve this problem, which contains different regularization. To adapt fas...
