Diffuse Optical Tomography (DOT) is a medical imaging technique that uses NIR light to measure the optical properties of biological tissue. By analyzing light absorption and scattering from chromophores like hemoglobin, it enables non-invasive, real-time imaging of tissue oxygenation, composition, and functional activity.
Miniaturized optics for satellites and CubeSats are compact, lightweight systems enabling high-resolution imaging, beam steering, and spectral sensing within strict size, power, and mass limits, allowing small satellites to perform advanced, cost-effective space missions.
Optical Communication in Space: From Free-Space Lasers to Deep-Space Data Links
Optical communication in space represents a transformative shift from traditional radio frequency (RF) transmission to high-speed, laser-based data exchange. Using light instead of radio waves, these systems can send vast amounts of data across interplanetary distances with unparalleled efficiency.
Collectively referred to as Free-Space Optical Communication (FSOC), this technology uses modulated laser or LED beams to transmit digital information wirelessly through open space. Within this broad category, space-based laser communications (often called lasercomm) focus on orbital and satellite applications, while Deep Space Optical Communication (DSOC) pushes the frontier even farther—to interplanetary distances.
