Two-dimensional light-distribution measurement with a 90° cornered knife edge
Applied Optics
|September 11, 2010
Abstract:
An aperture-scanning technique for determining a two-dimensional light distribution is described. Results are obtained by moving a wedge-shaped, knife-edge aperture and comparing measurements from adjacent scans. The scanning procedure described herein overcomes deficiencies inherent in alternative methods that use a two-dimensional detector array or one-dimensional motion of a knife-edge aperture.

Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
Two-Dimensional Microscopy in Microbiology
Two-dimensional (2D) microscopy encompasses a range of optical techniques that capture images within a single focal plane, offering detailed representations of microscopic structures. These techniques are essential in biological and medical research, enabling the visualization of cellular and subcellular structures with different levels of contrast and specificity.There are several major types of 2D microscopy, each with strengths and applications.Bright-Field MicroscopyBright-field microscopy...
