Abstract: Optical systems, receivers, devices, and methods including a free space beam combining and polarization splitting prism to receive local oscillator light and optical signals in substantially parallel input paths that are in the same plane and output two orthogonally polarized beams in substantially parallel output paths that are substantially perpendicular to the plane of the input paths. Light in one of the incoming paths is reflected toward a combining surface that combines the local oscillator light and the optical signal. The combined beam then encounters a polarization splitting surface that splits the combined beam into two orthogonally polarized beams. One of the polarized beam may be reflected 90 degrees in plane and then both orthogonally polarized beams are reflected 90 degrees of out of plane to output each orthogonally polarized beam into substantially parallel optical output paths.

Abstract: A 3D scanner for recording topographic characteristics of a surface of at least part of a body orifice, where the 3D scanner includes a main body having a mounting portion; a tip which can be mounted onto and un-mounted from the mounting portion, where the tip is configured for being brought into proximity of the body orifice surface when recording the topographic characteristics such that at least one optical element of the tip is at least partly exposed to the environment in the body orifice during the recording; and a heater for heating the optical element, where the heat is provided by way of thermal conduction; where the tip can be sterilized in a steam autoclave when un-mounted from the main body of the 3D scanner such that it subsequently can be reused.
