Telescope Resolution vs. Aperture and Wavelength @HuygensOptics

Huygens Optics | Telescope Resolution vs. Aperture and Wavelength @HuygensOptics | Uploaded January 2022 | Updated October 2024, 1 hour ago.
Discussion about of the fundamental limitations imposed by aperture and wavelength on the maximum sharpness of a telescope. By discussing the energy mechanisms behind diffraction, I try to explain why this relationship exists. In the last part I discuss the implications for the recently launched James Webb telescope. Contents:
0:00 Intro
2:43 Short experiment with aperture
4:47 About angular resolution
7:44 Resolution comparison of 3 different telescopes
10:13 Diffraction phenomena explained using energy as a basis
14:08 Experiment showing edge diffraction in real aperture
17:14 The James Web resolution explained using aperture and wavelength

Light & Coherence part 2: Spatial Coherence (and the Double Slit Experiment)

$Making Optical Logic Gates using Interference In this video I look into the idea of using optical interference to construct different kinds of logic gates, both from a conceptual- as well as from the practical perspective. Contents 0:00 Intro 2:15 Logic gate operation 3:36 Optical logic gates 4:45 Concept of a diffractive logic gate 7:52 Practical aspects (photolithography and etching) 8:46 Wave front observation method 9:20 Results 13:51 Possible applications Webpage with detailed and complete information on logic gates: http://www.ee.surrey.ac.uk/Projects/CAL/digital-logic/gatesfunc/index.html The diffractive patterns were made by using a home-brewed windows Zone plate app and then modifying them further with photoshop. The Zone Plate app can be downloaded from: http://www.huygensoptics.com/assets/zp_writer.zip For Windows 10 and for personal use only. Virus scanners and Windows will nag about it being a rare / unknown file and make installation sometimes difficult. Sorry about that. Install this app at your own risk. An overview article on various known optical logic gates can be found in this paper: https://www.hindawi.com/journals/aot/2014/275083/ However it does not contain any mention of the configuration described in this video The video contains references to detail videos on the following subjects: Photolithography: https://youtu.be/Lf-ev2Fop_k Chromium photomask etching: https://youtu.be/foMT8gLYxBY Other diffractive optics (photon sieves): https://youtu.be/TshYfYIxR9E Microscope viewing method: https://youtu.be/TshYfYIxR9E$
