Abstract
A laser Doppler interferometer was built for the precise measurement o f intraocular optical distances in humans and chicks, A technique usin g Purkinje images was developed to position the chick's eye reproducib ly. A computer algorithm for the objective analysis of the interferenc e signal and determination of the optical distances is presented. The precision of this noncontact interferometric method for measuring the cornea-retina distance is better than +/-20 mu m
