The sparse array elements selection in sparse imaging of circular-array photoacoustic tomography

open access: yesJournal of Innovative Optical Health Sciences, 2022
Photoacoustic imaging (PAI) has been developed, and photoacoustic computed tomography (PACT) is widely used for in vivo tissue and mouse imaging. Simulated annealing (SA) algorithm solves optimization problems, and compressed sensing (CS) recovers sparse signals from undersampled measurements. We aim to develop an advanced sparse imaging framework for

Curved Computer-Generated Integral Imaging Based on Backward Ray-Tracing Technique

open access: yesIEEE Photonics Journal, 2023
In traditional computer-generated integral imaging (CGII) methods, the generated elemental image array (EIA) is flat, and it doesn't fit for curved integral imaging (II) systems. Here, a curved CGII method was proposed for curved II system. In the

End-to-End Optimization of an Achromatic Diffractive Optical Element Array for Integral Imaging Three-Dimensional Display

open access: yesIEEE Photonics Journal, 2022
Diffractive optical element (DOE) array promises compact shape for full-parallax integral imaging three-dimensional (3D) display. However, DOEs suffer from large chromatic aberration due to the strong wavelength-dependent nature of diffraction phenomena ...

Flexible ultrasound transceiver array for non-invasive surface-conformable imaging enabled by geometric phase correction

open access: yesScientific Reports, 2022
Ultrasound imaging provides the means for non-invasive real-time diagnostics of the internal structure of soft tissue in living organisms. However, the majority of commercially available ultrasonic transducers have rigid interfaces which cannot conform ...

Effects of Number of Lenses in Microlens Arrays on Field of View in Integral Imaging Systems

open access: yesInternational Journal of Automation and Smart Technology, 2015
In integral imaging, the microlens array (MLA) is the key element for capturing 3D information. The microlens array can be used to encode light originating from different directions into the photosensor, producing images called elemental images.
