From Light to Mind: Sensors and Measuring Techniques in Confocal Microscopy
This article outlines the most important sensors used in confocal microscopy. By confocal microscopy, we mean "True Confocal Scanning", i.e. the technique that illuminates and measures one single…Read article
Towards Digital Photon Counting Cameras for Single-molecule Optical Nanoscopy
A SPAD array camera with single-photon sensitivity and zero read-out noise allows for the detection of extremely weak signals at ultra-fast imaging speeds. With temporal resolution in the order of…Read article
Multi-Images Deconvolution Improves Signal-to-Noise Ratio on Gated Stimulated Emission Depletion Microscopy
Time-gated detection, namely, only collecting the fluorescence photons after a time-delay from the excitation events, reduces complexity, cost, and illumination intensity of a stimulated emission…Read article
Gates Open for Improved Confocal Fluorescence and Super-Resolution STED
True confocal microscope systems feature single-point illumination and single-point detection. The method is called "optical sectioning" since the generated image contains only information from the…Read article
