In brief, OCT angiography uses motion contrast by comparing the decorrelation signal between multiple B-scans obtained at each retinal cross-section to detect blood flow, employing the principle that theoretically, only ...

Two straight line is used to draw the Optical Cross at 90 apart from each other. These two lines represent two principal meridians of eye. Most people have vertical (90°) & Horizontal meridian
Optical coherence tomography (OCT) is a noninvasive diagnostic technique that renders an in vivo cross-sectional view of the retina. OCT utilizes a concept known as interferometry to create a cross
High-class microscope objectives can be composed of a set of individual lenses, lens dou-blet and triplet groups that are ce-mented together in order to reach the optical specifications that are designed for.
Optical cross section is useful in fields such as LIDAR. In the field of radar this is referred to as radar cross-section. Objects such as license plates on automobiles have a high optical cross section to
This page introduces the optical principles necessary to understand the design and performance of astronomical telescope systems — the telescope and eyepiece used as a visual instrument with the
Learn how ZEISS filter sets, light sources, and fluorophores relate to each other using interactive overviews and spectra. Infinity corrected microscopes have been the industry standard
There are two common methods to determine which aperture in a system serves as the system stop: The first method is to image each potential stop into object space (use the optical surfaces between
Two straight line is used to draw the Optical Cross at 90 apart from each other. These two lines represent two principal meridians of eye. Most people have vertical (90°) & Horizontal meridian
The optical cross-connection box is a new product developed and designed based on the working principle of the original copper wire optical cable cross-connection box and the current optical cable
Though this design is much more complicated than its finite conjugate counterpart, it allows for the introduction of optical components such as filters, polarizers, and beamsplitters into the optical path.
Be careful to keep track of which meridian is being neutralized when using sciascopy bars or loose lenses; it may be helpful to draw the powers on an optical cross and then convert it to a lens
