Rethinking data-driven point spread function modeling with a differentiable optical model

1 code implementation9 Mar 2022 Tobias Liaudat, Jean-Luc Starck, Martin Kilbinger, Pierre-Antoine Frugier

Even though observations of the PSF are available at some positions of the field of view (FOV), they are undersampled, noisy, and integrated in wavelength in the instrument's passband.

Rethinking the modeling of the instrumental response of telescopes with a differentiable optical model

1 code implementation24 Nov 2021 Tobias Liaudat, Jean-Luc Starck, Martin Kilbinger, Pierre-Antoine Frugier

By adding a differentiable optical forward model into the modeling framework, we change the data-driven modeling space from the pixels to the wavefront.
