1. An ophthalmic imaging system comprising:
a first imaging subsystem configured to form a primary image of the interior of an eye through the diameter of the eye pupil;
a sensor array; and
a second imaging subsystem comprising a lens array configured to form an array of secondary images on the sensor array;
wherein the optical distance between the lenses and the sensor array (b), the diameter of the lenses (d), the diameter of the eye pupil (D), the optical distance between the object plane to be imaged and the eye lens (e) and the minimum radius of circle required to cover the lens array with circles having the minimum radius if the circles were centred on the centres of the lenses (R) obey the relation, b
