A targeted imaging system has been developed for applications requiring recording from stationary samples at high spatiotemporal resolutions. It works by illuminating regions of interest in rapid sequence, and recording the signal from the whole field of view onto a single photodetector. It can be implemented at low…

High-resolution optical imaging of deep tissue in-situ such as the living brain is fundamentally challenging because of the aberration and scattering of light. In this work, we develop an innovative adaptive optics three-photon microscope based on direct focus sensing and shaping that can accurately measure and…

Multidimensional photography can capture optical fields beyond the capability of conventional image sensors that measure only two-dimensional (2D) spatial distribution of light. By mapping a high-dimensional datacube of incident light onto a 2D image sensor, multidimensional photography resolves the scene along with…

Fluorescence microscopy enables specific visualization of proteins in living cells and has played an important role in our understanding of protein subcellular location and function. Some proteins, however, show altered localization and/or function when labeled using direct fusions to fluorescent proteins, making them…

'Vladimir Parshin' 'Petr Zemlyanukha' 'Giacomo Oliveri'] A new approach to millimeter-wave imaging was suggested and experimentally studied. This approach can be considered as the evolution of the well-established focal-plane array (FPA) millimeter-wave imaging. The significant difference is the use of a…

Developments in direct electron detector technology have played a pivotal role in enabling high-resolution structural studies by cryo-EM at 200 and 300 keV. Yet, theory and recent experiments indicate advantages to imaging at 100 keV, energies for which the current detectors have not been optimized. In this study, we…

We present direct-LIVE-PAINT, an easy-to-implement approach for the nanoscopic imaging of protein structures in live cells using labeled binding peptides. We demonstrate the feasibility of direct-LIVE-PAINT with an actin-binding peptide fused to EGFP, the location of which can be accurately determined as it transiently…

Direct electron detectors (DEDs) have revolutionized cryo-electron microscopy by facilitating correction of beam-induced motion and radiation damage and by providing high-resolution image capture. A new generation of DEDs has been developed by Direct Electron, the DE64, that has good performance in both integrating and…

Electrochemical reactions are the unrivaled backbone of next generation energy storage, energy conversion and healthcare devices. However, the in-situ real-time visualization of electrochemical reactions, which can shed light on various critical unknown insights on the electrochemical processes, still remains the…

Single-Pixel Detectors Authors: ['Julie Belleville' 'Prachi Thureja' 'Harry A. Atwater'] We introduce a conceptual framework for a lensless imaging system which employs an active metasurface as a high-frequency, continuously tunable amplitude and phase modulation aperture, coupled to a discrete single-pixel detector.…

Many exciting terahertz imaging applications, such as non-destructive evaluation, biomedical diagnosis, and security screening, have been historically limited in practical usage due to the raster-scanning requirement of imaging systems, which impose very low imaging speeds. However, recent advancements in terahertz…

Dark-field X-ray imaging visualizes structural inhomogeneities through small-angle scattering, but existing directional methods are confined to the micrometer scale. While recent advances have extended dark field capabilities to nanoscale transmission X-ray microscopy, directional scattering retrieval - critical for…

Battery research increasingly relies on advanced imaging, yet open access to such data remains rare, scattered across various sources, and difficult to find. The Battery Imaging Library (BIL) is the first open, curated collection of multi-modal and multi-length scale battery imaging datasets, accompanied by a…

'Liu Dong' 'Zhu Wenyue'] A novel technique for the simultaneous fusion, imaging and encryption of multiple objects using a single-pixel detector is proposed. Here, encoded multiplexing patterns are employed to illuminate multiple objects simultaneously. The mixed light reflected from the objects is detected by a…

'Stephen Marshall' 'Wojciech Roga' 'John Jeffers' 'Daniel K. L. Oi'] In this paper we present an evolution of the single-pixel camera architecture, called 'pushframe', which addresses the limitations of pushbroom cameras in space-based applications. In particular, it is well-suited to observing fast moving scenes while…

A cloneable NanoParticle (cNP) is an inorganic nanoparticle that is synthesized by a protein. The protein determines the elemental composition, size, morphology, and other properties of the nanoparticle. Here, we describe the use of a cloneable Selenium NanoParticle (cSeNP) as a cloneable imaging contrast agent in…

Fluorescent imaging, a key technique in life science research, frequently utilizes fluorogenic probes for precise imaging in living systems. Tetrazine is an effective emission quencher in the design of fluorogenic probes, which can be selectively damaged upon bioorthogonal click reactions, leading to considerable…

Determining complete atomic structures directly from microscopy images remains a longstanding challenge in materials science. MicroscopyGPT is a vision-language model (VLM) that leverages multimodal generative pre-trained transformers to predict full atomic configurations including lattice parameters, element types…

Fig. 1. We introduce a method that uses time-of-flight (ToF) imagers not for measuring scene depth, but rather as analog computational imagers that can directly measure difference values at a pixel level. We demonstrate this principle with a slightly modified ToF camera system (a), where simple reconfigurations in the…

'Songyu Sun' 'Mona Jarrahi' 'Aydogan Özcan'] A unidirectional imager would only permit image formation along one direction, from an input field-of-view (FOV) A to an output FOV B, and in the reverse path, BA, the image formation would be blocked. Here, we report the first demonstration of unidirectional imagers…

'Jannis N. Ahlers' 'Ying Ying How' 'Stephanie A. Harker' 'Kaye S. Morgan'] In recent years, a novel x-ray imaging modality has emerged that reveals unresolved sample microstructure via a “dark-field image”, which provides complementary information to conventional “bright-field” images, such as attenuation and…
