Modern Types of Axicons: New Functions and Applications
Sensors, 2021 Axicon is a versatile optical element for forming a zero-order Bessel beam, including high-power laser radiation schemes. Nevertheless, it has drawbacks such as the produced beam’s parameters being dependent on a particular element, the output beam’s ...

Using Diffractive Optical Elements [PDF]
Optik & Photonik, 2018 AbstractA diffractive optical element (DOE) uses thin micro‐structure patterns to alter the phase of the light that is propagated through it. Those micro‐structures, once properly designed, can manipulate the light to almost any desired intensity profile or shape.

Multiple Optical Trapping by Means of Diffractive Optical Elements
Japanese Journal of Applied Physics, 2004 In this paper we report multiple optical trapping of microscopic dielectric particles using diffractive optical elements implemented on twisted nematic liquid crystal spatial light modulators. The particles are trapped in arrays disposed in plane or in volume and can be moved independently in x-y-z by changing the configuration of the diffractive ...

Off-Axis Diffractive Optics for Compact Terahertz Detection Setup
Applied Sciences, 2020 Medical and many other applications require small-volume setups enabling terahertz imaging. Therefore, we aim to develop a device for the in-reflection examination of the samples.
