1. A method of processing light, comprising:
- a. receiving a first portion of light from a source of said light;
b. masking a portion of said first portion of said light so as to form a masked first portion of said light so as to prevent said portion of said first portion of said light from propagating with a remainder of said first portion of said light in said masked first portion of said light;
c. receiving at least one second portion of said light, wherein said at least one second portion of said light is subject to scattering by a medium from a corresponding at least one interaction region of said medium, said at least one second portion of said light is generated by said source of said light prior to being subject to said scattering by said medium, and said first portion of said light is not subject to said scattering by said medium from said at least one interaction region of said medium;
d. combining said masked first portion of said light with said at least one second portion of said light along a substantially common direction of propagation;
e. generating a first interference pattern from said masked first portion of said light; and
f. generating at least one second interference pattern from said at least one second portion of said light, wherein said masked first portion of said light is configured so that said first and said at least one second interference patterns are substantially mutually exclusive, and said first interference pattern would otherwise overlap said at least one second interference pattern if the operation of combining was performed absent the operation of masking said portion of said first portion of said light.

Abstract
A portion of a first portion of light (13, 90, 90′) from a source of light (11) is masked by a mask (138), and the resulting masked first portion of light (90″) is combined using a beam splitter optic (136) with at least one second portion of the light (30) that had been subject to scattering by a medium (20, 20′, 20″). The mask (138) is configured so that interference patterns (104, 47) generated from the first and at least one second portions of light are substantially mutually exclusive even though those interference patterns (104, 47) would otherwise overlap one another absent the mask (138).

52. A system for processing light, comprising:
-
a. a first mask, wherein said first mask provides for either absorbing or reflecting a portion of a first portion of light from a source of said light so as to provide for forming a masked first portion of said light from which is excluded said portion of said first portion of said light; b. a first beam splitter optic, wherein said first beam splitter optic is located in relation to said first mask so as to provide for combining along a substantially common direction of propagation said masked first portion of said light with at least one second portion of said light, said at least one second portion of said light is subject to scattering by a medium from a corresponding at least one interaction region of said medium, said at least one second portion of said light is generated by said source of said light prior to being subject to said scattering by said medium, and said first portion of said light is not subject to said scattering by said medium from said at least one interaction region of said medium; and c. an interferometer, wherein said interferometer is located so as to provide for receiving said masked first portion of said light and said at least one second portion of said light from said first beam splitter optic, said interferometer provides for generating a first interference pattern from said masked first portion of said light; and
said interferometer provides for generating at least one second interference pattern from said at least one second portion of said light, wherein said first mask is configured so that said first and said at least one second interference patterns are substantially mutually exclusive, and said first interference pattern would otherwise overlap said at least one second interference pattern absent said first masklight. - View Dependent Claims (57, 59, 60, 63, 64, 65, 68, 69, 72, 73, 74, 75, 79, 80, 81, 84, 85, 86, 87, 91, 92)
