Abstract
An endoscope assembly with a main imaging device and a first light source is configured to provide a forward view of a body cavity, and further includes a detachable imaging device with an attachment member engageable with the distal end region of the endoscope, a linking member connected to the attachment member, and an imaging element with a second light source, wherein the detachable imaging device provides a retrograde view of the body cavity and the main imaging device. Light interference is reduced by using polarizing filters or by alternating the on/off state of the main imaging device, the first light source, the imaging element and the second light source so that the main imaging device and first light source are on when the imaging element and second light source are off and the main imaging device and first light source are off when the imaging element and second light source are on.
