Single-pixel imaging (SPI), which is generally based on computational imaging, has the advantages of a wide bandwidth and ability to image objects beyond visual field. However, major challenge in developing SPI large number illumination patterns that are required. Unlike traditional relies random measurement patterns, method proposed this letter involves two-step phase shift reduces greatly required patterns. Theoretical analysis shows 6724 reconstruct 128 × 128-pixel whose peak...
In practical application environments, objects are rarely stationary, which makes it difficult to image dynamic with conventional single-pixel imaging (SI) techniques. this paper, a rotationally synchronized (RS-SI) method is proposed object in rotation. The modulation pattern rotates sync the rapidly rotating object, and center of rotation ensured be line illumination pattern. Then, RS-SI reconstruction algorithm used reconstruct by collecting light reflected from object's surface. This...
Acinetobacter baumannii, a gram-negative bacterium, is notorious for causing severe infections with high mortality rates. Rapid and accurate detection of A. baumannii crucial prompt treatment, effective infection control, curbing antibiotic resistance. However, there no suitable method rapid easy on-site baumannii. The DNA Endonuclease Targeted CRISPR Trans Reporter (DETECTR) system offers rapid, precise, sensitive approach to by integrating the target-specific recognition capabilities...
Real-time computational ghost imaging (CGI) has received significant attention in recent years to overcome the trade-off between long acquisition time and high reconstructed image quality of CGI. Inspired by compound eyes, we propose a parallel with modulation patterns multiplexing permutation achieve faster high-resolution With permutation, several small overlapping fields-of-view can be obtained; meanwhile, difficulty alignment illumination light field multiple detectors well resolved.

Single-pixel imaging (SPI), which uses a photodetector to detect the reflected total light intensity of set structured illumination patterns modulated by target scene, provides method for visible waveband imaging, hyperspectral and terahertz imaging. However, it faces challenge when scene be imaged has specular reflections. To deal with this problem, multi-angle without feature matching is presented. With method, location detector does not affect image reconstruction, results reconstruction...
