(For digital sampling fans this is a consequence of Nyquist’s theorem.)

The reconstructed RGB signals may still further be improved with regard to colored aliasing according to the Nyquist-theorem.

Frequently this is called the Shannon sampling theorem, or the Nyquist sampling theorem, after the authors of 1940s papers on the topic.

Nyquist’s theorem states that you need a sampling rate of

The “how can two sampling points resolve 20 kHz?” argument is an untutored misinterpretation of the Nyquist-Shannon sampling theorem.

Arbitrary waveform and function generators are normally specified by sample rate (e.g. GSample/s), which is converted to the RF domain by the Nyquist factor of two.

This is achieved by processing a sequence of angular-position-dithered frames to generate a high-definition, Nyquist-sampled, integrated image for each of the polarizations.
