This indicates that if we want to get a higher transverse (along x axis) image resolution (i.e., evanescent waves with higher [k.sub.x] (and thus higher [k.sub.z]) to be recovered at the image position), the depth of focus
of planar superlens will drop more rapidly.
Chapters offer a depth of focus
and detail on the major themes begun and created by Fitzgerland's approach and writings which lend particularly well to school research as well as understanding his writings.
Photron has unveiled a microscopy camera system that has been designed to increase the depth of focus
displayed According to the company, a piezoelectric actuator physically moves the objective lens at a rate of 30 times per second while the camera records at the 1,000 frames per second (fps) resulting in approximately 30 fps, each with a different focal point.
Jason Brooks' giant portraits with their careful simulation of a camera's limited depth of focus
are heavily indebted to Chuck Close.
The Quick Image 2D non-contact video measurement system uses a telecentric lens that, compared to conventional optics, provides a wider field of view and greater depth of focus
. The result, reduced focusing effort, translates into error suppression and increased speed for higher measuring throughput.
The company's Deep-View technique permits the microscope's depth of focus
to be drastically increased almost in real time.
The rocket-launched SEALEM radar reflectors (remember, they don't call it chaff anymore) simulate the parameters of the protected ship for radio-frequency polarization, spectral fluctuation, and platform area and depth of focus
. The effect is sustained for 40 seconds at a distance of 200 meters for centroid seduction and up to 1,800 meters for distraction-seduction.
When you reduce the diameter of the diaphragm the depth of focus
The ImageCAM is designed with an extended depth of focus
system that keeps images in focus without camera adjustment.
In recent developments, the use of lasers has been found to produce a huge depth of focus
and pure colors, with an RGB output produced by diode-pumped solid-state (DPSS) lasers combined with nonlinear optical frequency converters.
