Disclosed herein is a method of determining the near angle scattering of a sample reflective surface comprising the steps of: a) splitting a beam of light having a coherence length of greater than or equal to about 2 meters into a sample beam and a reference beam; b) frequency shifting both the sample beam and the reference beam to produce a fixed beat frequency between the sample beam and the reference beam; c) directing the sample beam through a focusing lens and onto the sample reflective surface, d) reflecting the sample beam from the sample reflective surface through a detection restriction disposed on a movable stage; e) recombining the sample beam with the reference beam to form a recombined beam, followed by f) directing the recombined beam to a detector and performing heterodyne analysis on the recombined beam to measure the near-angle scattering of the sample reflective surface, wherein the position of the detection restriction relative to the sample beam is varied to occlude at least a portion of the sample beam to measure the near-angle scattering of the sample reflective surface. An apparatus according to the above method is also disclosed.

A structure allowing multiple optical paths through an optical isolator or the like with substantially no interaction. A lens collimates light from a first multiple fiber optic path termination. The collimated light is processed by an optical isolator unit or another optical processing unit such as a coupler. The processed light is reimaged onto a second multiple fiber optic path termination. Preferably, the optical paths in the first termination are in one-to-one correspondence with the optical paths in the second termination.
