Fig. 5. Diagram of the experimental setup. The LED is the light source, and the target moves and rotates through three-axis motorized stages. The collecting lens projects the image of the target onto the DMD for modulation, and the modulated light intensity is collected on the PMT by the converging lens. The PMT converts the optical signal into an electrical signal, which is captured by the acquisition card and sent to the computer.
