Figure 3
Schematics of the optical set-ups. The helicity of incident light on the MS is controlled by the relative angle between the linear polarizer and the quarter waveplate. In these images right handed circularly polarized light is shown. (a) To make efficiency measurements the light scattered by the MS is collected by a f = 25.4 mm lens and the intensity is measured with a Thorlabs S130C Photodiode Power Sensor (b) To photograph the holographic image the light scattered from the MS is projected onto a screen.
