Optics and Photonics

Our data and instrumentation help designers understand the fundamental physics of new systems, validate aeronautics computational and life models, and improve optical space communications for human and robotic explorations.

Overview

Our data leads to improved designs, validation and verification of systems performance, increased communications, safety and security, and reduced design cycle times for many of the core technologies developed at NASA.
