Moreover, reversing the direction of electron bunch will make the emitted light from the proposed structure to switch from a convergent beam to a divergent beam. Finally, the formation of a convergent beam containing red, green and blue lights just above the chirped gratings is also demonstrated...

Since such light beam (LB) which impinges upon the scanning lens group (40) is divergent light which diverges within the main scanning surface, it is possible to correct a curvature of field of an image surface (IS) and obtain an excellent drawing quality....

A method of recording chirped volume gratings by a convergent beam and a divergent beam is studied. Theoretical study of this recording method for chirped volume gratings is made and the expression of the period of chirped volume grating is derived. The influence of the parameters of the ...
Skiascopy apparatus has the illuminating light beam periodically changed between a convergent and a divergent state. The observation beam is collected and the time course of both beams is compared to measure the faulty vision of the eye. Pref. the illuminating beam is continuously varied between ...
Method of microlithography with the use of divergent/convergent beams for holographic restoration of an imageThe invention describes a method of manufacturing a holographic mask capable of producing an image pattern that contains elements of a subwavelength size along with decreased deviations from the ...

Techniques for forming high contrast X-ray and / or gamma ray radiation images are provided.The image is minimal contribution from the object dependent background radiation.In this disclosure, a low divergent quasi single energy X-ray or gamma ray output from a laser Compton light source is ...
The shapes of single lens surfaces capable of focusing divergent and collimated beams without aberration have already been calculated. However, nanofocusing compound refractive lenses (CRLs) require many consecutive lens surfaces. Here a theoretical example of an X-ray nanofocusing CRL with 48 ...
