Performance comparison of aperture-less and confocal infrared microscopes
Journal of Spectral Imaging, 2019 We compared hyperspectral infrared raster maps and images for contrast, definition and resolution of the same samples recorded with a confocal microscope coupled with a synchrotron radiation source vs a Focal Plane Array (FPA) detector equipped ...

Implementation and Optimization of a Dual-confocal Autofocusing System
Sensors, 2020 This paper describes the implementation and optimization of a dual-confocal autofocusing system that can easily describe a real-time position by measuring the response signal (i.e., intensity) of the front and the rear focal points of the system. This is

Confocal laser speckle autocorrelation imaging of dynamic flow in microvasculature
Opto-Electronic Advances, 2022 Laser speckle imaging has been widely used for in-vivo visualization of blood perfusion in biological tissues. However, existing laser speckle imaging techniques suffer from limited quantification accuracy and spatial resolution.

Chromatism and confocality in confocal microscopes
Scanning, 1992 AbstractIn confocal microscopes, whenever a broadband light source is used, or when excitation and detection are performed at different wavelengths, for example in fluorescence, then the influence of microscope objective chromatism on the degree of confocality is very important.

Introduction to Confocal Microscopy [PDF]
Journal of Investigative Dermatology, 2012 Conventional microscopy requires viewing a thin-cut “section” of fixed or frozen tissue, and therefore cannot be used to view thick tissue samples or for in vivo investigations. In vivo microscopy requires a virtual, rather than a physical, section of the specimen.

Frontiers in Plant Science, 2014 Plant leaves are optically complex, which makes them difficult to image by light microscopy. Careful sample preparation is therefore required to enable researchers to maximise the information gained from advances in fluorescent protein labelling, cell ...
