Camera System Resolution and its Influence on Digital Image Correlation

A Proposed Simple Teleradiology System Using a Digital Camera

Background & Aims: Teleradiology as an efficient way for avoiding unnecessary transfer of patients to special medical centers requires the images with digital format. However, in some developing countries, including Iran, imaging is being done using non digital devices. In such cases, changing analog images into digital ones can solve the problem. The method which is nowadays used for digita...

image resolution in the digital era: notion and clinical implications

digital radiographs need additional metadata in order to be accurate when being converted to analog media. resolution is a major reason of failures in proper printing or digitizing the images. this letter shortly explains the overlooked pitfalls of digital radiography and photography in dental practice, and briefly instructs the reader how to avoid or rectify common problems associated with res...

On the Use of Acoustic Emission and Digital Image Correlation for Welded Joints Damage Characterization

A series of tests have been conducted to investigate fatigue damage characterization in corroded welded steel plates using structural health monitoring (SHM) techniques. Acoustic Emission (AE) is a non-destructive testing (NDT) technique with potential applications for locating and monitoring fatigue cracks in service. In the present work, AE is implemented to characterize damage during crack e...

Digital Mapping Camera System

Digital camera system on a chip

of activity in the area of CMOS image sensors has taken place. Up until recently, the dominant, and nearly the only, solid-state image sensor technology was the charge-coupled device (CCD). However, most microprocessors, logic circuits, ASICs, and memory circuits are based on CMOS technology. Now CMOS can be used for image sensors in a rapidly expanding sphere of applications. Several important...
