Endoscope field of view measurement
Biomedical Optics Express, 2017 The current International Organization for Standardization (ISO) standard (ISO 8600-3: 1997 including Amendment 1: 2003) for determining endoscope field of view (FOV) does not accurately characterize some novel endoscopic technologies such as endoscopes with a close focus distance and capsule endoscopes.

All-spherical telescope with extremely wide field of view
, 2015 An all-spherical catadioptic system made of glass of one type is proposed for the monitoring of large sky areas. We provide an example of such a system with the aperture of diameter 400 mm and the curved field of 30 degree in diameter.Comment: 4 ...

Full-field structured-illumination super-resolution X-ray transmission microscopy
, 2019 Modern transmission X-ray microscopy techniques provide very high resolution at low and medium X-ray energies, but suffer from a limited field-of-view.

Theoretical Research on Large Field-of-View Polarization Imaging Based on Dynamic Vision Sensors
PhotonicsThe combination of dynamic vision sensors (DVSs) and polarization can overcome the limitation of DVSs whereby they can only detect dynamic scenes, and it also has the ability to detect artificial targets and camouflaged targets, and is thus expected to ...

Elliptical field‐of‐view PROPELLER imaging [PDF]
Magnetic Resonance in Medicine, 2009 AbstractTraditionally two‐dimensional scans are designed to support an isotropic field‐of‐view (iFOV). When imaging elongated objects, significant savings in scan time can potentially be achieved by supporting an elliptical field‐of‐view (eFOV). This work presents an empirical closed‐form solution to adapt the PROPELLER trajectory for an eFOV.

A Field View of Soil - Digging Around [PDF]
, 2003 The purpose of this resource is to understand that variations in landscape can affect soil properties. Students investigate variations in the soils around their school to discover that soil properties like moisture and temperature exhibit considerable ...

PSF and field of view characteristics of imaging and nulling interferometers
, 2010 In this communication are presented some complements to a recent paper entitled "Simple Fourier optics formalism for high angular resolution systems and nulling interferometry", dealing with imaging and nulling capacities of a few types of multi-aperture

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

The Astrophysical JournalThe nonlinear coupling between stellar convection and rotation is of great interest because it relates to understanding both stellar evolution and activity. We investigate the influence of rotation and the Coriolis force on the dynamics and thermodynamic
