چکیده

We present a novel sensor that measures the entire spatial coherence function within an aperture by use of a variable astigmatic lens. This sensor permits digital capture and processing of partially coherent fields. We demonstrate the sensor by sampling and computing the coherent modes of a three-dimensional incoherent source.

Digital refraction distortion correction with an astigmatic coherence sensor.

We demonstrate the sensing and correction of an isoplanatic refractive distortion (not lens aberrations), using the complete measurement of the partially coherent field in an aperture that the previously described astigmatic coherence sensor provides. Isoplanatic distortions, and in general distortions that do not cause energy loss, maintain the orthogonality of the coherent modes. We use the f...

3D high-density localization microscopy using hybrid astigmatic/ biplane imaging and sparse image reconstruction.

Localization microscopy achieves nanoscale spatial resolution by iterative localization of sparsely activated molecules, which generally leads to a long acquisition time. By implementing advanced algorithms to treat overlapping point spread functions (PSFs), imaging of densely activated molecules can improve the limited temporal resolution, as has been well demonstrated in two-dimensional imagi...

Design and Manipulation 3D Imaging System by using Photodiode Grid

Introduction: Radiation imaging is one of the applicable methods in diagnostic medicine and nondestructive testing for industrial applications. In nondestructive 3D imaging, in addition to the radiation source, there is a requirement for a suitable detection system, data acquisition system, mechanical sections for moving objects, reconstruction algorithm and finally a computer for processing an...

In vitro Comparison of Conventional Film and Direct Digital Radiography in Proximal Caries Detection

Introduction: Various systems for intraoral digital radiography have been available as an alternative to film–based radiography. In consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of im‌age quality and elimination of processing, it has been extensively used in different fields of denti‌stry in recent years. The purpose of this study wa...

The Application of Multi-Layer Artificial Neural Networks in Speckle Reduction (Methodology)

Optical Coherence Tomography (OCT) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. An inherent characteristic of coherent imaging is the presence of speckle noise. In this study we use a new ensemble framework which is a combination of several Multi-Layer Perceptron (MLP) neural networks to denoise OCT images. The noise is...
