High-speed high-resolution plasma spectroscopy using spatial-multiplex coherence imaging techniques (invited)

High-speed high-resolution plasma spectroscopy using spatial-multiplex coherence imaging techniques

We have recently obtained the first simultaneous 2-d plasma Doppler spectroscopic images of plasma brightness, temperature and flow fields. Using compact polarization optical methods, quadrature images of the optical coherence of an isolated spectral line are multiplexed to four quadrants of a fast CCD camera. The simultaneously captured, but distinct images can be simply processed to unfold th...

Polarized Neutron Set-up with Variable Energy and Resolution and High Polarization and Intensity

A polarized neutron set-up is proposed with a focusing curved mirror system to increase the intensity and to obtain an electronically adjustable energy and energy resolution. The set-up consists of 3 curved neutron mirror systems with 2 Drabkin monochromators in between. The 3 mirror systems, necessary to optimize such a double Drabkin monochromator, in addition focus the neutron beam in 2 dire...

Brain Imaging Techniques: Invasiveness and Spatial and Temporal Resolution

Investigation of the Spatial Resolution and Field of View with Change of Magnification in VRX CT

Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV). An important factor that limits the spatial resolution of the VRX CT is the effect of focal spot size. Also, the optimum magnification is different at each incident a...
