ABSTRACT:
Biological tissue is imaged by non-damaging illumination from a coherent ht source and retroreflective radiation from a phase conjugate mirror without correction for absorption induced distortion. Optics is provided to regulate the illumination and to direct the retroreflective imaging radiation from the targeted biological tissue. Such imaging radiation is maintained substantially at unity reflectivity.
