摘要
A freeform surface off-axial three-mirror image-side telecentric optical system comprises a primary mirror, a secondary mirror, a tertiary mirror and an image sensor. The secondary mirror is the aperture stop. A reflective surface of the primary mirror is a fourth-order polynomial freeform surface of xy. Each of a reflective surface of the secondary mirror and a reflective surface of the tertiary mirror is a sixth-order polynomial freeform surface of xy.
