Deflectometry Measurement System for analysis of reflector surface slope error.
This non-contact method allows for accurate and quick measurements of mirror shape accuracy and therefore the assessment of concentration quality Mirror panel Deflectometry:
Field-Version Deflectometry: Reflection of the absorber tube is used instead of projected patterns and permits a robust and simple application of the method for measurements in existing trough fields (with lower accuracy).
Heliostat Field Deflectometry:An automated system allows for the measurement of many or all heliostats within an existing field during one night (depending on circumstances of the field).
The Photogrammetry Measurement System
The Photogrammetry Measurement System is a flexible, portable and non-tactile tool for the accurate geometry evaluation of large structures and surfaces.
Additional methods characterize the torsion stiffness and similar parameters of a structure.
