Abstract:
|
For some industrial applications, an accurate estimation
of a light source position is needed. That is the case for a
heliostat, a device that projects sunlight onto a focus hundreds
of meters away from its aiming point. In this paper, we present
a novel sensor design for generating an alignment error signal.
Included is a detailed study of its response, which shows that
certain geometrical design parameters are necessary to achieve
desired accuracy. This sensor has been implemented using microelectromechanical
system techniques to achieve a robust structure
at low cost and it has been successfully applied to sun-tracking
systems. Experimental results obtained in field tests are included. |
