Abstract
Provided are modular volume holographic imaging system (VHIS) endoscopic systems, comprising: an endoscope attachment module having a microscope objective lens, a single or cascaded compensated relay system configured to preserve an optical wavefront for use with a single or multiplexed volume hologram to select wavefronts originating from different object depths, and a system aperture; and a handle module configured to be reversibly attachable for operative communication with the endoscope attachment module, and having a beam splitter; a relay having adjustable spacing for object space focus compensation, and a single or multiplexed volume hologram suitable in operation to select wavefronts originating from different object depths, and wherein the handle module is further configured for operative communication with an illumination source and imaging optics. Preferably, an illumination module and an imaging module are configured to be in operative, reversibly attachable communication with the handle module. Flexible tip endoscopic embodiments are provided.
