Light source, optical device, measuring device, robot, electronic apparatus, movable structure, and manufacturing apparatus

This invention describes a light source made from many tiny lasers, called surface-emitting lasers. Each laser has its own small light detector built on the same base material, allowing it to measure its own light output. The design specifically includes a detector for each laser, positioned to receive light directly from it, and can also feature lasers emitting different colors of light.

Why it matters: Since 2019, the demand for compact, integrated optical sensing modules has surged, particularly in robotics and advanced manufacturing, including additive manufacturing. This invention's integrated design of lasers and detectors on a single substrate offers the miniaturization and precision now highly valued for these evolving applications.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
