Optical coherence tomography. A high-resolution spectral-domain OCT scan (3×3 mm) of a dry age-related macular degeneration eye showing geographic atrophy and drusen in macula on both cross-sectional and en face fly-through. Optical coherence tomography ( OCT) is an imaging technique that uses interferometry with short- coherence-length light ...
PerkinElmer. PerkinElmer, Inc., previously styled Perkin-Elmer, is an American global corporation that was founded in 1937 and originally focused on precision optics. Over the years it went into and out of several different businesses via acquisitions and divestitures; these included defense products, semiconductors, computer systems, and others.
Optical projection tomography is a form of tomography involving optical microscopy. [1] The OPT technique is sometimes referred to as optical computed tomography (optical-CT) and optical emission computed tomography (optical-ECT) in the literature, to address the fact that the technique bears similarity to X-ray computed tomography (CT) and ...
The average household size was 2.91 and the average family size was 3.25. The age distribution is 31.5% under the age of 18, 2.8% from 18 to 24, 25.6% from 25 to 44, 27.9% from 45 to 64, and 12.2% who were 65 years of age or older. The median age was 40 years. For every 100 females, there were 93.9 males.
This variation is called vignetting, and can be corrected by selectively brightening the perimeter of the image. Flat-field correction ( FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital ...
Super-resolution imaging. Super-resolution imaging ( SR) is a class of techniques that enhance (increase) the resolution of an imaging system. In optical SR the diffraction limit of systems is transcended, while in geometrical SR the resolution of digital imaging sensors is enhanced.
