The capability to perform high-resolution, wide field-of-view (FOV) microscopy imaging is highly sought after in biomedical applications. In this paper, we report a wide FOV microscopy system that uses a closed-circuit-television (CCTV) lens for image relay and a flatbed scanner for data acquisition. We show that such an imaging system is capable of capturing a 10 mm × 7.5 mm FOV image with 0.7...

In this paper, the flocking problem in a network of double-integrator agents with limited angular fields of view (FOV) is investigated. The angular FOV represents the limitation imposed on the velocity sensor mounted on every agent in the network, while the position sensors are assumed to be omnidirectional. To increase the sensing capabilities of agents and preserve network connectivity, it is...

Introduction: Multi-Echo FLASH imaging in combination with echo train shifting [1,2] offers BOLD sensitivity for matrix sizes up to 256 x 256 leading to in-plane resolutions of about 1 mm. Long measurement times and low Signal-to-Noise-Ratio (SNR) preclude BOLDfMRI going to higher resolutions. Hence, only a reduction in the Field-of-View (FOV) further increases spatial resolution. Latter, howev...

The choice of receiver coils used in high-field CMR, such as at 3T, is critical. Because of reduced RF penetration, a broader surface area is required. Too large an area requires imaging with a large FOV, which increases scan-time. This can often be reduced with parallel reconstruction techniques, or k-t space techniques (if the additional FOV is relatively stationary). A simple solution is to ...

Background Myocardial arterial spin labeling (ASL) is a non-contrast CMR technique for measuring myocardial blood flow (MBF), but has relatively low signal-to-physiological noise (PN). Therefore perfusion measurements are made over several averaged pixels within left ventricular (LV) segments and not individual pixels. Shorter image acquisition times using SENSE parallel imaging has been shown ...

A compound eye and retina-like combination sensor based on a space-variant curved micro lens array (CMLA) is proposed to simultaneously offer the large FOV characteristic of a compound eye and retina-like feature of a single aperture eye. The mathematical models of the sensor are developed and the structure parameters of the space-variant CMLA are deduced. Modeling verification is carried out a...

An investigation into the optical wireless system performance has been carried out for both a conventional hybrid system (CHS) with a single detector under various receiver fields-ofview (FOV) and a pyramidal fly-eye diversity receiver (PFDR) with different FOVs. Original results for a hybrid system that employs a PFDR, under different FOVs, are presented. It is demonstrated, through FOV optimi...

Abstract Purpose LGBTQ + people who have experienced intimate partner violence (IPV) and family of origin (FOV) are known to face significant barriers reporting or seeking support for these experiences may not always feel supported when do so. Method Data from 4,607 participants a nationwide survey adults in Australia indicated having ever IPV FOV was analysed. Multivariable logistic regression...

Wide field-of-view (FOV) optics are essential components in many optical systems, with applications spanning imaging, display, sensing, and beam steering. Conventional refractive wide FOV often involve multiple stacked lenses, resulting large size weight as well high cost. Metasurface lenses or metalenses promise a viable solution to realizing without complex lens assembly. We review the variou...

Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...
