WebJul 1, 2005 · This is very different from cylindrical lens where the central tube gives the strongest beam intensity. With increasing distance from the lens exit, X-ray beams start to be focused. This is similar to situation with the cylindrical lens. However, extent of “focusing” by the parallel beam lens is much weaker than that of the cylindrical lens. WebWe present a new, to the best of our knowledge, type of off-axis digital holographic imaging method with a long field of view (FOV). In the method, the pre-magnification recording geometry is realized by a cylindrical lens (CL) or cylindrical beam instead of a conventional objective or spherical beam in traditional off-axis digital holography (DH).

Webbeam so that the energy is efficiently redistributed from the beam center to the edges in the far field (which is usually begins at 100 mm from the last lens surface). This can be seen clearly in the ray trace diagram (see Figure 4.) Because a Powell lens is a type of cylindrical lens, it only homogenizes the beam in one dimension.

WebBoth types use either cross-cylindrical or square microlens arrays to divide the incident beam into beamlets. These beamlets are then passed through a spherical lens FL to be overlapped at the homogenization plane FP located in the back focal plane of the spherical lens FL.
