Laser Safety Calculations for Imaging Sensors [PDF]
Sensors, 2019 This publication presents an approach to adapt the well-known classical eye-related concept of laser safety calculations on camera sensors as general as possible. The difficulty in this approach is that sensors, in contrast to the human eye, consist of a variety of combinations of optics and detectors. Laser safety calculations related to the human eye

Glass Substrate Dust Removal Using 233 fs Laser-Generated Shockwave
Micromachines, 2021 Eliminating dust is gaining importance as a critical requirement in the display panel manufacturing process. The pixel resolution of display panels is increasing rapidly, which means that even small dust particles on the order of a few micrometers can ...

Polarimetric fiber laser sensors [PDF]
Optics Letters, 1993 The beating between the eigenpolarization modes from a fiber laser is used to demonstrate an active, polarimetric sensor with direct frequency output. For the measurement of lateral stress applied to the jacketed Nd-doped fiber laser, a sensitivity of 4.8 kHz/g with a good linearity is obtained.
