The photographic optical system has at least one diffractive optical element. Assuming that a wavelength at which the diffraction efficiency of the diffractive optical element reaches a maximum is defined as a design wavelength &lgr;.sub.DOE, it satisfies the following condition:0 < E.sub.1 (&...

1. Data is first encoded in the time domain as a series of optical pulses. This pulse train is then injected into an optical fiber where it is partially reflected by a series of Rayleigh scattering centers. This distributed backscattering process randomly mixes the elements in the input vector...
A diffractive optical element such as a diffuser, diffraction grating, and/or hologram, can be manufactured by using a surface relief pattern on a surface of a surface relief tool. A layer of curable material is physically contacted with the surface relief pattern on the surface of the surface...
Beam shaping techniques are based on refractive [1], [2], [3], [4], diffractive [5], [6], [7], [8], [9], [10], [11], [12], [13] and even absorptive elements [14]. Usually, beam shaping using a Diffractive Optical Element (DOE) operates on 2-D mode, that is a ...

Yasuyuki Ichihashi & Ryutaro Oi As the demand for computational performance in artificial intelligence (AI) continues to increase, diffractive deep neural networks (D2NNs), which can perform AI computing at the speed of light by repeated optical modulation with diffractive optical elements (DOEs...
Lastly, diffractive elements are frequently expensive and difficult to produce, and this is particularly the case when the diffractive element must be constructed to fit into a small area, such as a distal tip of a surgical probe for surgical instruments that are 23-gauge or smaller. Thus, ...
