Publikováno v: Adaptive Optics Systems V.

The CANARY-Hosted Upgrade for High-Order Adaptive Optics (CHOUGH), is a narrow-field of view High- Order Single Conjugate on-sky AO demonstrator to be placed on the 4.2m WHT telescope. It aims to produce a Strehl ratio greater than 0.5 in the visible

Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extremely Large Telescopes. Such systems have multiple wavefront sensors o

Publikováno v: AIP Conference Proceedings.

A print is a mark, or drawing, made in or upon a plate, stone, woodblock or other material which is cover with ink and then is press usually into a paper reproducing the image on the paper. Engraving prints usually are image composed of a group of bi

Improved Pseudo-colored Engraving Print Method

Autor: Daniel Hölck, Joaquim Barbé, Niklaus Ursus Wetter, Jaime Frejlich

Publikováno v: AIP Conference Proceedings.

The engraving prints made by intaglio and relief techniques usually appear as black and white images consisting of a huge number of binary lines. Various textures and gray scales are obtained by changing the direction and densities of the lines in th
