An optical endoluminal far-field microscopic imaging catheter comprises a light generating system, a first light delivery conduit for propagating light generated by the light generating system and a light distributor configured to redirect light propagated by the delivery conduit into a direction of an object to be imaged. A discriminator is configured for capturing light reflected from the object incident on a window of the discriminator from a particular direction and transmitting only the light captured from the particular direction to a second light delivery conduit. A drive mechanism is configured to sweep the window through a plurality of directions in a predictable pattern for matching each light capture event in the window with a direction of the window during the event. An analyzer matches the direction of the window with an associated light capture event and generate a visible image based on a mosaic of the captured light.
