spatial filter

However updating the region involved in the spatial filter for a moving client could cause a lot of traffic.

In scientific applications, a spatial filter can be used to reduce speckle.

The device is similar to a spatial filter.

From there, the laser light is fed into a very long spatial filter to clean up the resulting pulse.

Spatial filters and image processing operations were used to enhance the aggregate edges.

From spatial filters to mirror symmetry: New findings and a new model.

Laser applications include spatial filters, Q-switching, high intensity x-ray control.

SAM is a nonlinear beamforming approach which can be thought of as a spatial filter.

Our question regards to what degree one can seperate the spatial filter functions before face recognition becomes impossible.

The spatial filter is held under vacuum in order to eliminate the creation of plasma at the focus (pinhole).

For instance a spatial filter removes either high, medium or low spatial frequencies from an image.

The light source image is focused onto the plane of the spatial filter. which then becomes the light source for the system.

It did not use spatial filters to smooth the beam after amplification stages and thus had a fairly poor beam quality.

Even though zones restrict the event traffic somewhat we want to be able to further restrict traffic using spatial filters.

Argus passed its light through a series of amplifiers, with spatial filters between each stage and easily achieved terawatt beam powers.

It is the use of spatial filters that lead to the long beamlines seen in ICF laser devices.

Imaging spatial filters are, in effect, small inverted telescopes inserted in the laser beam to focus the light through a pinhole.

Kernels are often used as spatial filters, each one tuned to a specific spatial frequency that the convolution is intended to highlight.

An airy pattern is produced by defocussing the pinhole of the spatial filter, and the central spot is selected with an aperture.

To produce coherent light he passed the monochromatic light from an emission line of a mercury-vapor lamp through a pinhole spatial filter.

Examples include acousto-optic modulators for cavity dumping and vacuum spatial filters for transverse mode control.

After passing through a number of amplifiers the light pulse is "cleaned up" in a spatial filter before being fed into another series of amplifiers.

High-pass filter: A spatial filter which selectively enhances contrast variations with high spatial frequencies in an image.

Each beamline consisted of a series of Nd:glass amplifiers separated by spatial filters and other optics for cleaning up the resulting beams.

After the light had passed through the final amplifier and spatial filter it was then used for experiments in the target chamber, lying at one end of the apparatus.
