The optical quality of concentrators has a direct impact on the thermal efficiency of
concentrating solar power plants. There is a need to evaluate the quality of the mirrors …

Strong efforts are being made to drive heliostat cost down. These efforts are summarised to
give an update on heliostat technology comprising: determination of wind loads, heliostat …

A coupled thermal–mechanical model based on the Eulerian formulation is developed for
the steady-state dissimilar friction stir welding (FSW) process. Multiple phase flow theories …

Incorporating the modal and zonal estimation approaches into a unifying scheme, we
introduce an improved three-dimensional shape reconstruction version of specular surfaces …

Optical accuracy is a primary driver of parabolic trough concentrating solar power (CSP)
plant performance, but can be damaged by wind loads, gravity, error during installation, and …

The deflectometry provides a powerful metrological technique enabling the high-precision
testing of reflective surfaces with high dynamic range, such as aspheric and freeform …

The deflectometry provides a feasible way for surface testing with a high dynamic range, and
the calibration is a key issue in the testing. A computer-aided testing method based on …

In this paper, we introduce a flexible and simple system calibration method for specular
surface metrology based on the combination of reflection rays determined by the varied …

Concentrated solar power (CSP) offers potential for low-cost dispatchable renewable energy
generation, if costs can be significantly reduced from current levels [1–3]. Solar tower CSP …

The performance of a heliostat field is directly related to the optical quality of the mirror
surfaces used to reflect solar radiation onto the receiver. In this paper, two methods are used …
