Abstract Space optical instruments play a pivotal role in enhancing our understanding of the
universe and our planet, and are crucial in addressing the urgent challenges posed by …

Stray light is a critical aspect for high performance optical instruments. When stray light
control by design is insufficient to reach the performance requirement, correction by post …

Stray light (SL) has emerged as a primary limiting factor for space telescopes. Pre-launch
testing is essential for validating performance and identifying potential issues. However …

In high performance optical instruments, post-processing methods are employed to reduce
the stray light (SL) level below what can be achieved by design. Often, algorithms are limited …

As a common but troublesome branch of stray light, ghost images in catadioptric optical
systems greatly limit the performances of such optics, including panoramic annular lenses …

ARRAKIHS is an ESA mission dedicated to observing dwarf galaxies and stellar streams. Its
objective will be to test the standard cosmological model, particularly regarding the nature of …

Stray light (SL) control is an important aspect in the development of optical instruments.
Iterations are necessary between design and analysis phases, where ray tracing simulations …

The Multi-directional, Multi-polarization, Multi-spectral Imager (3MI) is one of the payloads
that will be on board of the MetOp-SG “Satellite A”, developed to provide information on …
