Time-of-Flight: Highly Reliable 3D Imaging for Challenging Applications

There are multiple technologies based on the ToF concept. Generally, all of them are synchronized with a light source and estimate the distance by calculating the time taken for the light to travel from the camera to the object and then back again.

Challenges of Fabricating and Coating Laser Crystals

Because laser crystals are sensitive optical components and are often used with high-power lasers, depositing the correct coatings onto them without introducing any defects is essential.
