A testbed for heliostat facets alignment by target reflection.

This work describes a lab-scale testbed designed and built to assess a heliostat canting detection technique based on target reflection. The installation consists of two structures supporting; 1) target facet and camera, and 2) object facet. The testbed integrates a high-resolution camera connected to a computer to detect canting errors. Other equipment includes a laser alignment system, micrometer screws for canting adjustment, and an inclinometer for camera levelling. Additionally, the testbed incorporates a wireless camera control system to remotely adjust the camera zooming and focusing via a web interface. [ABSTRACT FROM AUTHOR]
