Abstract
For optically interrogating substances overlaid by turbid media, a method of wavefront manipulation by means of binary phase masking is proposed. Through altering the degree of mode matching between the fields reaching the collection optics and the field distribution of the propagation mode of single-mode waveguides, the proposed method can be used to suppress the collection of short-range light originated near the collection optics while permitting unimpeded collection of light originated from sites substantially behind turbid media. General description of the principles is accompanied by a numerical modeling. A group of binary phase masks, mutually orthogonal, are introduced for practical applications.
