Multi-Dot Projector

Multi-dot and Multi-line Structured Light Patterns

Osela’s Multi-Dots and Multi-Line pattern are based on a combination of Diffractive (DOE) and refractive optics. The DOE efficiently splits the beam with a precise angular spacing while maintaining the properties (dimension, divergence, and polarization) of the input laser. The DOEs are high quality diffraction gratings etched directly into fused silica providing stability over time and temperature as required in the most demanding industrial applications.
