collimated beam उदाहरण वाक्य

The TOF analysis requires the beam to be pulsed through the mechanical chopper, producing collimated beam'packets'that have a'time-of-flight'( TOF ) to travel from the chopper to the detector.
For instance, a plano-convex lens, which is used to focus a collimated beam, produces a sharper focal spot when used with the convex side towards the beam source.
The integrals of spectral radiance ( or specific intensity ) with respect to solid angle, used above, are singular for exactly collimated beams, or may be viewed as Dirac delta functions.
Most important among them is a collimated or focused light beam ( usually from a laser source producing a collimated beam of monochromatic light ) that illuminates a region of the sample.
This is the size, in the imaging plane, of smallest object that the lens can resolve, and also the radius of the smallest spot to which a collimated beam of light can be focused.

For comparison, in the parabolic type of antenna a feedhorn at the end of a waveguide directs a conical beam of output energy toward the reflector, whence it is focused into a narrow collimated beam.
The integrals of specific ( radiative ) intensity with respect to solid angle, used for the definition of spectral flux density, are singular for exactly collimated beams, or may be viewed as Dirac delta functions.
A collimated beam of light from a light source ( ASTM D1003-Illuminant C, BS EN ISO 13468 Parts 1 and 2-Illuminant D65 ) passes through a sample mounted on the entrance port of an integrating sphere.
In operation, the gun cathode is the source of thermally-emitted electrons that are both accelerated and shaped into a collimated beam by the electrostatic field geometry established by the gun electrode ( grid and anode ) configuration used.
For the present purposes, the light from a star can be treated as a practically collimated beam, but apart from this, a collimated beam is rarely if ever found in nature, though artificially produced beams can be very nearly collimated.
