Wide field retinal imaging has emerged as a transformative technology over the last few decades, revolutionizing our ability to visualize the intricate landscape of the retina. By capturing expansive retinal areas, these techniques offer a panoramic view going beyond traditional imaging methods. In this review, we explore the significance of retinal imaging-based biomarkers to help diagnose ocular and systemic conditions.

The York University Teledyne Optech (YUTO) Mobile Mapping System (MMS) Dataset, encompassing four sequences totaling 20.1 km, was thoroughly assembled through two data collection expeditions on August 12, 2020, and June 21, 2019. Acquisitions were performed using a uniquely equipped vehicle, fortified with a panoramic camera, a tilted LiDAR, a Global Positioning System (GPS), and an Inertial Measurement Unit (IMU), journeying through two strategic locations: the York University Keele Campus in Toronto and the Teledyne Optech headquarters in City of Vaughan, Canada.

Each view of our environment captures only a subset of our immersive surroundings. Yet, our visual experience feels seamless. A puzzle for human neuroscience is to determine what cognitive mechanisms enable us to overcome our limited field of view and efficiently anticipate new views as we sample our visual surroundings.

Research on endogenous auditory spatial attention typically uses headphones or sounds in the frontal hemispace, which undersamples panoramic spatial hearing. Crossmodal attention studies also show that visual information impacts spatial hearing and attention. Given the overlap between vision and audition in frontal space, we tested the hypothesis that the distribution of endogenous auditory spatial attention would differ when attending to the front versus back hemispace.

Article Synopsis
- Researchers are developing artificial compound eyes (CE) modeled after arthropods to improve imaging technology, but current designs have issues with defocusing when used with standard CMOS cameras.
- A new compact camera inspired by South American shrimps utilizes a deep learning method to achieve clear wide-field imaging without complex hardware, significantly simplifying its design.
- The innovative camera, weighing only 5.4g and measuring 3 x 3 cm, shows superior resolution and 3D trajectory tracking, making it suitable for applications in nano-optics, medical endoscopy, and robotics.
