ABSTRACT:
A system for collecting solar radiation includes a laser source for emitting, along a preselected path, radiation having a wavelength absorbable by at least one type of atmospheric molecule. Radiation directing components such as lenses or deformable mirror segments are disposed in the transmission path for directing the laser radiation from the source to a predetermined target region of the atmosphere located a pre-established distance above a surface of the earth. Control componentry is operatively connected to the directing components for controlling the operation thereof to modulate an index of refraction of air in the predetermined target region of the atmosphere to produce in that region a predetermined refractive index pattern such as an atmospheric Fresnel lens for concentrating incoming solar radiation on a solar energy collector. The control componentry is operatively connected to the laser source for timing the emission of radiation therefrom. Sensors are provided for detecting the distribution of the radiation concentration by the atmospheric lens. Feedback circuitry is operatively connected to the sensors and to the beam directing components for modifying the operation thereof in response to signals from the sensors to compensate in real time for changes in atmospheric refractive index arising from atmospheric turbulence, thereby optimizing concentration of solar radiation by the atmospheric region onto the collector.
