Surface roughness in high-precision optics refers to microscopic surface irregularities that critically affect light behavior, causing scattering, distortion, and reduced performance, making ultra-smooth finishes essential for optimal optical efficiency.
Durable optical materials are essential for modern systems operating in harsh environments, providing stability against radiation, temperature extremes, and mechanical stress while ensuring reliable, high-performance optical functionality.
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.
