Sebastian Achim Mueller

TL;DR
This paper proposes a novel 71-meter Cherenkov-plenoscope using light-field plenoptic perception to significantly lower the gamma-ray energy threshold and improve three-dimensional imaging, overcoming current structural and optical limitations.
Contribution
It introduces a new large-scale Cherenkov telescope design employing plenoptic perception, enabling lower energy thresholds and enhanced 3D reconstruction capabilities.
Findings
Achieves an energy threshold of 1 GeV for gamma-rays.
Reduces structural rigidity requirements for large telescopes.
Enables 3D reconstruction with a narrower depth-of-field.
Abstract
Telescopes -- far seeing -- have since centuries revealed insights to objects at cosmic distances. Adopted for gamma-ray-astronomy, ground based Cherenkov-telescopes image the faint Cherenkov-light of air-showers induced by cosmic gamma-rays rushing into earth's atmosphere. In the race for the lowest possible energy-threshold for cosmic gamma-rays, these Cherenkov-telescopes have become bigger, and now reached their physical limits. The required structural rigidity for image-quality constrains a cost-effective construction of telescopes with apertures beyond 30 meter in diameter. Moreover, as the aperture increases, the narrower depth-of-field irrecoverably blurs the images what prevents the reconstruction of the cosmic particle's properties. To overcome these limits, we propose plenoptic-perception with light-fields. Our proposed 71 meter Cherenkov-plenoscope requires much less…
