interferometry, showing how geometric and positioning errors propagate into measurement uncertainty and proposing improved calibration procedures [ 12 ]. Higuchi et al. present a sinusoidal phase modulation interferometer capable of measuring 2-dimensional in-plane displacements with sub-nanometer resolution at a sampling rate of 5 kHz. The system, based on high-speed cameras and electro-optic modulators, enables real-time analysis of dynamic deformations and air-induced wavefront aberrations, with potential applications in precision interferometry and astronomical instrumentation [ 13 ].
Finally, two articles delve into the modeling and computational design of structured light and resonant systems. Hofmann et al. propose an advanced iterative algorithm to derive phase masks that shape both beam intensity and thermal distribution in 3D, with relevance for amplifier engineering and laser processing [ 14 ]. Wu et al. contribute a theoretical analysis that starts from first principles to derive a full dynamical model of optical resonators from Maxwell’ s equations, bridging a gap between field theory and practical coupled-mode approximations [ 15 ].
We thank all the authors for their valuable contributions and the reviewers for their thoughtful assessments. We are confident that this collection will serve as a useful reference for researchers working at the forefront of optics and photonics, and a testimony to the scientific quality presented at EOSAM 2024.
