<p>An endoscope to perform non-tethered macroscopy and microscopy at the same time is provided. An electromagnetic source (110) is used to deliver electromagnetic energy through a first optical pathway to a tissue inside a body. An image detector (130) is used to detect the reflected electromagnetic energy from the tissue through a second optical pathway as realtime images. A macro-to-micro lens (150) set is used to change the magnification of the reflected electromagnetic energy before it reaches the image detector with two or more different magnification levels. A filter set (140) is used to filter the reflected electromagnetic energy before it reaches the image detector. Furthermore, the endoscope includes a flexible shaft (120). The distal end of the shaft includes a spread and spot means (410) to spread and spot the electromagnetic energy at the tissue. A processing means (640) is also included for processing the detected images.</p> |
