MEMS mirrors have a wide range of applications, most which require large field-of-view (FOV). Immersing in liquid is an effective way to improve the FOV. However, increased viscosity, convective heat transfer and thermal conductivity greatly affect dynamic behaviors electrothermally actuated micromirrors. In this paper, complex interactions among multiple energy domains, including electrical, t...

A novel approach to significantly increasing the field of view (FOV) of night vision goggles (NVGs) has been developed and demonstrated. This approach uses four image intensifier tubes instead of the usual two to produce a very wide 100 degree horizontal by about 4 0 degree vertical FOV. A conceptual working model, designated the Panoramic NVG, has been fabricated and evaluated.

We explored the destabilizing effect of visual field motion as the base of support (BOS) and the field of view (FOV) were narrowed. Visual field motion was achieved using an immersive virtual environment (scene) that moved realistically with head motion (natural motion) and translated sinusoidally at 0.1Hz in the fore-aft direction (augmented motion). Natural motion was presented in stereo whil...

The Imager on Board Integral Satellite (IBIS) is the imaging instrument of the INTEGRAL satellite, the hard-X/soft-gamma ray ESA mission to be launched in 2001. It provides diagnostic capabilities of fine imaging (12’ FWHM), source identification and spectral sensitivity to both continuum and broad lines over a broad (15 keV–10 MeV) energy range. It has a continuum sensitivity of 2 10 ph cm s a...

OBJECTIVE The purpose of this work is to evaluate the impact of optimization of magnification on performance parameters of the variable resolution X-ray (VRX) CT scanner. METHODS A realistic model based on an actual VRX CT scanner was implemented in the GATE Monte Carlo simulation platform. To evaluate the influence of system magnification, spatial resolution, field-of-view (FOV) and scatter-...

Existing OPAs are typically based on 2D rectangular arrays or 1D linear arrays. Both approaches present a limited field-of-view (FOV) due to the presence of grating lobes when element spacing is larger than λ/2. To address need for an increased steering range, we propose new design strategy OPA system utilizing circular phased array, with substantially FOV. We using demonstrated antenna design,...

Light Detection and Ranging (LiDAR) is widely used in the perception of physical environment to complete object detection tracking tasks. The current methods datasets are mainly developed for autonomous vehicles, which could not be directly roadside perception. This paper presents a 3D point cloud stitching method with wide horizontal field view (FoV) using LiDAR. Firstly, base model trained by...

This study investigated how display parameters influence humans’ ability to control simulated egorotations from optic flow. The literature on visual turn perception reports contradictory data, which might be partly due to the different display devices used in these studies. In this study, we aimed at disentangling the influence of display devices, screen curvature, and field of view (FOV) on th...

In this paper, we attempt to quantify the prognostic information embedded in multi-parametric histologic biopsy images to predict disease aggressiveness in estrogen receptor-positive (ER+) breast cancers (BCa). The novel methodological contribution is in the use of a multi-field-of-view (multi-FOV) framework for integrating image-based information from differently stained histopathology slides....

BACKGROUND AND PURPOSE 3-T MRI has been introduced into clinical examinations and is widely used [1]. High-resolution imaging is often essential as a clinical study for the diagnosis of diseases that show only subtle changes in the brain [2]. Since the 32-channel phased-array head coil offers a superb signal-to-noise ratio (SNR), high-quality images can be obtained when used with a 3-T MRI scan...
