Closed-loop control of heliostats with detailed radiant-footprint optimization
20 August 2024 • 10:30 AM - 10:50 AM PDT | Conv. Ctr. Room 18
Abstract
Retroreflectors ('retros') in front of the receiver provide feedback from multiple locations of each heliostat's radiant footprint thereon, simultaneously for all of them. The retros and their mounts are made of quartz glass to allow placement in the 'hot zone'.
To discriminate samples of light returned by multiple retros from each other and from the brightly lit receiver, the retro reflectivities are modulated at unique frequencies by spinning them.
The presentation will show component and system test results.
