A Generalized Expression for Accelerating Beamlet Decomposition Simulations
Jaren N. Ashcraft, Ewan S. Douglas, Ramya Anche +7
Paraxial diffraction modeling based on the Fourier transform has seen widespread implementation for simulating the response of a diffraction-limited optical system. For systems whe…
