Applications of Deployable Telescopes for Earth-observing Lidar

AstractNASA’s Advanced Component Technology (ACT) Program is funding the development and testing of the Deployable Optics Modeling Experiment (DOME) at the University of Colorado for developing and advancing to flight readiness high-precision deployable optics technology to enable space-based lidar measurements. In this project; precision deployment, microdynamic stabilization, and modeling tec...

Modelling Mineral Dust Using Stereophotogrammetry

Real, three-dimensional shape of a dust particle is derived from a pair of scanning-electron microscope images by means of stereophotogrammetry. The resulting shape is discretized, and preliminary discrete-dipole-approximation computations for the single dust particle reveal that scattering by such an irregular shape differs notably from scattering by a sphere or a Gaussian random sphere which ...
