After our article was published in January 2024, a notable astronomical event occurred on April 8, 2024: a total solar eclipse traversed the North America region. One of the authors, Arman Amirzhan, captured the eclipse at its totality using the meta-astrophotography apparatus. In this Addition, we report the eclipse images obtained with the 100 mm diameter metalens.

Non-planar illumination deflectometry for axicon metrology

|
By Henry T. Quach, Hyukmo Kang, Byeongjoon Jeong, Heejoo Choi
| optica.org
Abstract We introduce an on-axis deflectometry test configuration for axicon metrology. Axicons are challenging to measure due to their characteristically steep, convex geometry. However, if an axicon is coaxially aligned with a camera and a surrounding cylindrical illumination source, high-resolution surface measurements can be obtained via the principle of deflectometry.
