Phase Retrieval Utilizing Particle Swarm Optimization
Published 2018-01-01Get full textPhase retrieval is an important tool for image recovery techniques based on Fourier spectrum. Different iterative algorithms have been developed to retrieve phase information. However, due to the nonconvex feature of the phase optimization problem, it remains a challenge to globally obtain the optim...

A highly efficient SFFV promoter-driven mCherry-GFP-LC3B dual-fluorescence system for autophagy monitoring in erythroid cells
Published 2025-07-01Get full textObjective To develop a modified lentiviral expression system of mCherry-GFP-LC3B, driven by the hematopoietic-specific SFFV (spleen focus-forming virus) promoter, in order to perform an efficient and real-time monitoring of autophagy flux with in terminally differentiated erythroid cells. Methods Th...

Fast Optical Phased Array Calibration Technique for Random Phase Modulation LiDAR
Published 2019-01-01Get full textOptical phased array (OPA) imaging technique, which uses electro-optic modulation to achieve beam steering rather than mechanical scanning, is a raster scanning imaging method with great potential due to its noninertia and high speed. However, fabrication imperfection of an OPA causes pre-designed p...

Image Retrieval in Spatial and Temporal Domains With a Quadrant Detector
Published 2017-01-01Get full textTo retrieve an <italic>N</italic> pixel image of a scene, conventional digital cameras record the information using an <italic>N</italic> pixelated detector with one measurement, while single-pixel imaging achieves it by sampling the image in a particular basis and recording...
