1. In combination, an elongated endoscope probe for phase conjugate image formation at a proximal end of the probe, and a source of illuminating radiation disposed to illuminate an object near a distal tip of the probe, said probe comprising:

  • a first transmissive member extending from the distal tip of said probe to a filter location intermediate the distal tip of said probe and the proximal end of said probe;

    a second transmissive member extending from said intermediate filter location to the proximal end of said probe, wherein said first and second transmissive members exhibit substantially identical optical transmission characteristics; and

    a phase conjugate filter disposed at said intermediate filter location, between said first and second transmissive members.
