Field-averaging micro lenses that synthesize highly uniform illumination in coherent EUV optical systems. University of California, Applied Science and Technology. Center for X-ray optics, LBNL. Christopher N. Anderson (1), Patrick P. Naulleau (2), Paul Denham (2), Drew Kemp (2) and Senajith Rekawa (2) MOTIVATION.
6 Σεπ 2024 · These small lenses are tightly arranged together, forming an array that mimics the structure of compound eyes in insects, especially flies and other insects, hence the name. The design inspiration for compound eye lenses comes from the compound eye mechanism in nature.
31 Μαρ 2021 · The fly’s eye array is a useful optical element in illuminations systems, which can be used to create uniform irradiance distributions from non-uniform sources. This article applies the design of a fly's eye spactial light integrator to a digital projector and discusses the advantages and disadvantages of using such a system.
In this article, we propose the use of wideband Fly’s eye lens array architectures to generate multiple simultaneous fixed high-gain beams, in order to give coverage in future
10 Ιουλ 2019 · By using two pairs of fly-eye lenses, the light beam incident on the fly-eye lens is divided by the array lens and imaged on the irradiation surface. In this system, it is possible to irradiate light in a similar shape to a single lens and the intensity distribution becomes almost uniform.
1 Αυγ 2015 · The fly's-eye lens is designed in the shape of rectangle due to the shape of LCOS chip. Fly's-eye lens arrays are arranged in small uniformity lens arrays. Assume that ‘a’ and ‘b’ represent the width and height of fly's-eye lens (unit mm). M and N stand for the number of lens in horizontal and vertical direction.
