Visual receptor optics: Rhodopsin and pupil in fly retinula cells

The main theme of the present study has been the elucidation of the pupil mechanism of fly photoreceptor cells. It is argued in chapter 0 that essential elements in this system must be: the waveguide properties of the rhabdomeres, the visual pigment, the change in membrane potential generated by photopigment conversion, the resulting potential gradient in the sense cell and finally the properties of the retinula cell pigment granula, the latter effectuating the pupil action. ...
