3D imaging using scanning diffractometry

3D Scanning, Imaging, and Printing in Orthodontics

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...

3D Scanning Using Spatiotemporal Orientation

We present a new approach to volumetric scene reconstruction which can produce accurate models from turntable image sequences. Instead of an epipolar plane image (EPI) volume, we consider a function on the 4D spatiotemporal volume valued with the intensity back projection of the camera (time) to the particular voxel. Using an optical flow technique we compute the local orientation of this spati...

Second-Generation, Scanning, 3D Imaging Lidars Based on

Sigma Space is building a new generation of 3D imaging/polarimetric lidars based on photon-counting for use in small aircraft or mini-UAV’s. The most recent system is designed to provide contiguous, high resolution (15 cm horizontal, 3 cm vertical) 3D volumetric images of the underlying terrain on a single overflight from an altitude of 1 km. Based on prior experiments with a first generation N...

3D imaging of diatoms with ion-abrasion scanning electron microscopy.

Ion-abrasion scanning electron microscopy (IASEM) takes advantage of focused ion beams to abrade thin sections from the surface of bulk specimens, coupled with SEM to image the surface of each section, enabling 3D reconstructions of subcellular architecture at approximately 30nm resolution. Here, we report the first application of IASEM for imaging a biomineralizing organism, the marine diatom ...
