Abstract
An endoscope stereo imaging device includes an endoscope lens assembly and an imaging module. The imaging module includes first, second and third lens assemblies, a beam splitter, first and second image sensors and a micro lens array. A light beam from the endoscope lens assembly is transmitted to the beam splitter after passing through the first lens assembly and is split into first and second portions of the light beam. The first portion light beam is transmitted to the first image sensor via the second lens assembly and forms a two-dimensional image. The second portion light beam is transmitted to the second image sensor via the third lens assembly and the micro lens array sequentially and forms a first three-dimensional image.
