Single-axis combined shearography and digital speckle photography instrument for full surface strain characterization [PDF]

, 2005
Full characterization of the surface strain requires the measurement of six displacement gradient components of the surface strain tensor. The out-of-plane displacement gradient component may be directly measured using the full-field speckle ...

Image Processing Operators Based on the Gyrator Transform: Generalized Shift, Convolution and Correlation

Photonics, 2019
The gyrator transform (GT) is used for images processing in applications of light propagation. We propose new image processing operators based on the GT, these operators are: Generalized shift, convolution and correlation.

Temporal Co-Attention Guided Conditional Generative Adversarial Network for Optical Image Synthesis

Remote Sensing, 2023
In the field of SAR-to-optical image synthesis, current methods based on conditional generative adversarial networks (CGANs) have satisfying performance under simple scenarios, but the performance drops severely under complicated scenarios.

3D mechanical analysis of aeronautical plain bearings: Validation of a finite element model from measurement of displacement fields by digital volume correlation and optical scanning tomography [PDF]

, 2010
On Airbus aircraft, spherical plain bearings are used on many components; in particular to link engine to pylon or pylon to wing. Design of bearings is based on contact pressure distribution on spherical surfaces.

3D Gerchberg-Saxton Optical Correlation

IEEE Photonics Journal, 2018
Since Gerchberg–Saxton algorithm was developed, it has been applied in various fields, e.g., optical display and optical tweezers. In this paper, three-dimensional (3D) Gerchberg–Saxton optical correlation is proposed. A 2D image is divided
