Parameter Interpretation
- SDx: square root of the true deviation slope of the reflected light in the X direction (through the collector axis) compared with the slope of the ideal mirror surface, in mrad
- SDy: square value of the true deviation slope of the reflected light in the Y direction (along the direction of the heat collector) and the slope of the ideal mirror surface
- FDx: square value of the true focus deviation of the reflected light in the X direction (through the axis of the collector tube) compared with the ideal collector parabolic focal line, in mm
- FDy: square value of the true focus deviation of the reflected light in the Y direction (along the direction of the collector tube) and the ideal collector parabolic focal line, in mm
