We report a new technique for building a wide-angle, lightweight, thin-form-factor, cost-effective, easy-to-manufacture near-eye head-mounted display (HMD) for virtual reality applications. Our approach adopts an aperture mask containing an array of pinholes and a screen as a source of imagery. We demonstrate proof-of-concept HMD prototypes with a binocular field of view (FOV) of 70°×45°, or to...

We analyze the anisoplanatic adaptive receiver system field of view (FOV) and the possibility of controlling the system FOV by using an adaptive optics system with multiple wave-front sensors that sense wave-front phase aberrations of reference waves with different arrival angles. The conventional decoupled stochastic parallel gradient descent (D-SPGD) technique is generalized to include output...

Abstract Background While prior research has documented intimate partner violence (IPV) and family of origin (FOV) experienced by LGBTQ communities at rates least comparable to heterosexual and/or cisgender populations, little knowledge exists how this experience occurs within intersections these who is most risk. Methods This study utilised data from a large nationwide Australian survey the he...

1 We compare the diffraction-limited field of view (FOV) provided by four types of off-axis Gregorian telescopes: the classical Gregorian, the aplanatic Grego-rian, and designs that cancel astigmatism and both astigmatism and coma. The analysis is carried out using telescope parameters that are appropriate for satellite and balloon-borne millimeter and sub-millimeter wave astrophysics. We find ...

Program Executive Office Ground Combat Systems (PEO GCS) manages the development, systems integration, acquisition, testing, fielding, modernization and sustainment of the U.S. Army’s ground combat systems to provide world-class, affordable and relevant capabilities to soldiers and marines. Systems include the Abrams main battle tank, Bradley Family of Vehicles (FoV), self-propelled howitzers, ...

We present a novel foveated imaging system which consists of three major components: a foveated imager, a peripheral imager, and a 2D scanning sub-system. The foveated imager captures a narrow field of view (FOV) with high angular resolution to mimic the foveated region of interest (FRoI), and the peripheral imager captures a wide FOV with low angular resolution to provide the peripheral region...

Light sheet fluorescence microscopy provides optical sectioning and is widely used in volumetric imaging of large specimens. However, the axial resolution lateral Field View (FoV) system, defined by light sheet, typically limit each other due to spatial band product excitation objective. Here, we develop a simple multi-focus scheme extend FoV, where Gaussian can be focused at three or more cons...
