Fly photoreceptors; III. Angular sensitivity as a function of wavelength and the limits of resolution

Horridge, George Adrian; Mimura, K.; Hardie, R. C.


The angular sensitivity of single retinula cells of the eye of Calliphora and Eristalis has been measured by standard methods over the range of wavelengths that are visible to these flies. The point of using different wavelengths is to test the dependence of the angular sensitivity upon the width of the Airy disk of light which is focused on the receptors. The width of the Airy disk is determined by diffraction and proportional to wavelength. The seven best Calliphora retinula cells had a mean...[Show more]
