1. An assembly for measurements of one or more optical parameters of a medium, the assembly comprising:
a light sheet generator configured to provide a polychromatic light sheet comprising a light spectrum extending in a first spatial dimension, wherein the polychromatic light sheet has a propagation path in a second spatial dimension, wherein the light sheet generator comprises a light source configured to provide white light, a dispersive element configured to spread the white light in the first spatial dimension to provide the light spectrum, and an optical slit extending in the first spatial dimension configured to provide the polychromatic light sheet by limitation of the spread white light;
a light intensity modulator configured to provide an intensity modulated polychromatic light sheet by applying—to the polychromatic light sheet—an intensity modulation having a periodical, or substantially periodical, pattern in the first spatial dimension;
a holder for a sample of the medium, configured to enable the intensity modulated polychromatic light sheet to illuminate the sample; and
an optical sensor configured to record intensity of light exiting the sample over the light spectrum for provision of the one or more optical parameters.
