Abstract

A lens-sensor array for imaging parts of an eye comprises a lens array disposed onto a sensor array. The lens array transmits a light from a lens towards the sensor array. The lens array comprises a first section configured to direct the light reflected by a first part of the eye to the sensor array, and a second section configured to direct the light reflected by a second part of the eye to the sensor array. The first section comprises first sub-sections, each first sub-section comprising at least one first lenslet. The second section comprises second sub-sections, each second sub-section comprising at least one second lenslet. The sensor array comprises sensors that detect the light from the lens array and generate sensor signals corresponding to the light reflected by the first part of the eye and the light reflected by the second part of the eye.
