Fig. 2: Data workflow from a hologram to CD and ORD images.

From: Wide-field spectroscopic imaging of optical activity

Fig. 2

a, A hologram as recorded by the camera. The two dark squares are arrays of left- and right-handed chiral nanostructures, with a unit-cell design as shown in the insets. b, Amplitude images of the LCP (left) and RCP (right) components. c, Phase images of the LCP (left) and RCP (right) components. d, CD image obtained by taking the ratio of the LCP and RCP amplitude images. e, ORD image obtained by taking the difference between the LCP and RCP phase images. The measurements were acquired at a wavelength of 690 nm. Scale bar, 50 μm.
