Figure 2. Diagram of deep pseudopupil
This diagram is redrawn from one used in the laboratory of Dr. Doekele G. Stavenga where WSS was a research fellow in 1978. The original was drawn by Jan Witpaard, a former student of Dr. Stavenga. This drawing helps to demonstrate the optics of the deep pseudopupil as characterized by Franceschini and Kirschfeld [32,47].
