Light Engineering and Silicon Diffractive Optics Assisted Nonparaxial Terahertz Imaging (Laser Photonics Rev. 18(5)/2024)

Nonparaxial Terahertz Imaging Structured terahertz light in the form of an Airy beam – resembling the “THz sun” – illuminating Fresnel, Fibonacci and Bessel shaped THz beams illustrates the comprehensive study on THz light engineering in nonparaxial lensless imaging systems based on silicon diffractive optics (see article number 2301197 by Sergej Orlov, Rusnė Ivaškevičiūtė‐Povilauskienė, and co‐workers). The background depicts the numerically estimated modulation transfer map dependencies on the distance between imaged object and the optical element.
