Following laser surgery (photocoagulation) to repair a retinal tear, a person can typically expect a brief recovery period with minimal discomfort. Temporary symptoms may include mild irritation and ...

Recently, ceramic laser technology has emerged as a promising candidate because of its numerous advantages over single-crystal lasers. First, ceramics can be produced in large volumes, which makes ...

Femtosecond laser micromachining was first demonstrated in 1994, when a femtosecond laser was used to ablate micrometre-sized features on silica and silver surfaces 1,2. In less than ten years the ...

Abstract: Fringe projection profilometry (FPP) is a leading optical technique for high-speed and efficient 3-D measurements, crucial in automation for enhancing efficiency, quality, productivity, and ...

Abstract: The phase 3-D coordinate mapping (P3DM) is an efficient 3-D reconstruction method for the in situ measurement. However, the conventional P3DM calibration method requires complex operation or ...
