Abstract:
An optical probe for analyzing a sample illuminated by a laser, said probe comprising:an input optical fiber operably connectable to said laser, said input optical fiber having an entrance end and an exit end; a first beam splitter, said first beam splitter being adapted to transmit an alignment portion of a light beam from said input fiber exit end and to reflect a homodyning portion of said light beam from said input fiber; a lens between said input fiber exit end and said first beam splitter; a first and a second output optical fiber, each having an entrance end and an exit end, each exit end being operably connectable to respective optical detectors; and a second beam splitter, said second beam splitter being adapted to reflect at least a portion of said reflected homodyning portion into said output fiber entrance ends and to transmit light from said laser scattered by said sample into said entrance ends.
