1. A magnetic resonance examination system with an examination zone, the system comprising:
a monitoring system,
wherein the monitoring system comprises;
a camera, and
a non-metallic dielectric mirror, and
one of:
an adjustable pivot provided on an inner wall of the magnetic resonance examination system, wherein the non-metallic dielectric mirror is mounted on the adjustable pivot, or
a mechanical slide mechanism provided on the inner wall of the magnetic resonance examination system, wherein the mechanical slide mechanism is provided with a clamp to attach and/or detach the non-metallic dielectric mirror,
wherein the non-metallic dielectric mirror is disposed within the examination zone,
wherein the non-metallic dielectric mirror provides an optical pathway between a portion of the examination zone and the camera,
wherein the non-metallic dielectric mirror comprises a base plate having a macroscopically grated base on one side of the base plate,
wherein the macroscopically grated base comprises a plurality of patches,
wherein at least some of the patches are tilted at corresponding angles relative to a normal to a planar extension of the base plate,
wherein the corresponding angles determine a tilt to an angle of reflection for light from and/or to the examination zone.
