Patent abstract
An optical biometric sensor includes an array of light sensing elements, an array of diverging optical elements, and an array of apertures disposed between the array of light sensing elements and the array of diverging optical elements. Light incident on the diverging optical elements within a limited acceptance angle passes through the apertures and towards the light sensing elements and light incident on the diverging optical elements outside of the limited acceptance angle diverges away from the apertures.
