High-throughput high-dynamic range imaging by spatiotemporally structured illumination [PDF]
APL Photonics, 2022 Recent advances in biochemistry and optics have enabled observation of the faintest signals from even single molecules. However, although biological samples can have varying degrees of fluorescence expression ranging from a single to thousands of ...

Fast Mass Microscopy: Mass Spectrometry Imaging of a Gigapixel Image in 34 Minutes
, 2022 [Image: see text] Mass spectrometry imaging (MSI) maps the spatial distributions of chemicals on surfaces. MSI requires improvements in throughput and spatial resolution, and often one is compromised for the other. In microprobe-mode MSI, improvements in

Efficient image reconstruction for gigapixel quantum image sensors [PDF]
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014 Recent advances in materials, devices and fabrication technologies have motivated a strong momentum in developing solid-state sensors that can detect individual photons in space and time. It has been envisioned that such sensors can eventually achieve very high spatial resolutions (e.g., 109 pixels/chip) as well as high frame rates (e.g., 106 frames ...

Capturing and viewing gigapixel images [PDF]
ACM Transactions on Graphics, 2007 We present a system to capture and view "Gigapixel images": very high resolution, high dynamic range, and wide angle imagery consisting of several billion pixels each. A specialized camera mount, in combination with an automated pipeline for alignment, exposure compensation, and stitching, provide the means to acquire Gigapixel images with a standard ...

Noble Metals Doping in Lead-Free Double Perovskite Single Crystals: Achieving Near-Infrared to X-ray Broadband Photodetection. [PDF]
Small SciThis study examines the doping of Cs2AgBiBr6 double perovskite with noble metals (Au3+, Pd2+, and Ir3+). Significant redshifts in the absorption edge enable broadband photodetection from X‐rays to NIR, without abrupt changes in crystal structure. Au doping notably also enhances X‐ray sensitivity.

Service-based Processing of Gigapixel Images
CSRN, 2021 With the ongoing improvement of digital cameras and smartphones, more and more people can acquire high-resolution digital images. Due to their size and high performance requirements, such Gigapixel Images (GPIs) areoften challenging to process and explore compared to conventional low resolution images.
