In the world of precision sensing, a simple laser dot often isn’t enough. To truly understand a 3D environment, a machine needs structured information—lines, grids, or crosshairs that provide spatial context. This is where Diffractive Optical Elements (DOE) come in, acting as the high-precision "stencils" that transform a raw laser beam into a sophisticated tool for AI vision. For R&D teams working on Edge AI and multi-sensor fusion, selecting the right DOE module isn't just
