Patent ID: 8764633

Claim:
An apparatus comprising: a first image capture sensor comprising a first image capture sensor surface; a second image capture sensor comprising a second image capture sensor surface; a prism assembly, positioned to receive light, comprising: a distal face through which the received light enters the prism assembly; a beam splitter configured to reflect a first portion of the received light on a basis of a polarization state of the received light, and to transmit a second portion of the received light on the basis of the polarization state of the received light; and a surface configured to reflect the first portion of the received light onto the first image capture sensor, wherein the surface is separated from the beam splitter; and a reflective unit positioned to receive the second portion of the received light, the reflective unit being configured to direct the second portion of the received light to the second image capture sensor, wherein a first optical path length from the distal face to the first image capture sensor surface is about equal to a second optical path length from the distal face to the second image capture sensor surface; and wherein the first and second image capture sensor surfaces are coplanar.
