WebA fly's eye condenser (15) for converting an input light distribution into an output light distribution has at least one raster arrangement of optical groups (21, 22), of which at least some comprise means (30) suitable for changing polarization. The fly's eye condenser thus permits specific, location-dependent control of the polarization state of the output light … WebJun 3, 2002 · A fly's eye condenser system for uniform illumination. B.

WebSep 12, 2007 · We propose a new concept for fly's eye condensers incorporating a chirped tandem microlens array for the generation of a top-hat far field intensity distribution with improved homogenization under coherent illumination. The setup is compliant to reflow of photoresist as fabrication technique since plane substrates accommodating the arrays … When setting up the design, the user needs to decide how many channels to have in the vertical and horizontal directions in the array. The larger the number of channels, the more uniform the illumination at the illumination plane. However, the edges between the lenslets are not infinitely sharp, and so light gets … See more In digital projector design, we want to ensure that the digital source matches the projected image when it comes to the irradiance profile. This constraint therefore requires a projector … See more A fly’s eye array is a two-dimensional array of individual optical elements assembled into a single optical element. It is used to spatially transform light from a nonuniform … See more The following is a simple example of a real fly's eye illumination system for digital projector use.

WebNormally, fly’s eye condensers are used to homogenize light. However, in the case of fully coherent light, a fly’s eye condenser, in connection with some simple optical elements, such as a diffractive axicon, a grating, and a telescope, can be used as a quite flexible beam shaping system, forming arrays of rings, parts of rings, or other structures with varying … WebAug 1, 2008 · Abstract.
