Characterization of the nonlinear optical properties of Zn and Ag nanoparticles using light at 1550 nm

Results in Optics
Nonlinear optical properties of metallic and oxide metallic nanoparticles have been extensively studied as saturable absorbers in fiber-optic lasers in the infrared region for the generation of short and/or ultrashort pulses.

Analysis of refraction aware Neural Radiance Fields for 3D reconstruction of through the water scenes [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Neural Radiance Fields (NeRFs) synthesize novel views based on images acquired from different camera positions to represent 3D scenes. However, since they assume linear light paths, they are unsuitable for underwater environments where refraction causes ...
