Configuration of the LDAE system with 24 reflections on the high-energy-resolution crystal monochromator. In this figure, item 1 is the fixed base attached to the monochromator base; 2 is the moving sine-bar arm attached to the monochromator rotary shaft; 3 is the set of right-angle reflective prisms on the fixed base; 4 is the set of prisms on the moving arm; 5 is the axial retroreflector set on the fixed base; 6 is a custom-made commercial laser Doppler displacement meter with a heterodyne detector inside. |
