ABSTRACT:
An endoscope to perform non-tethered macroscopy and microscopy at the same time is provided. An electromagnetic source is used to deliver electromagnetic energy through a first optical pathway to a tissue inside a body. An image detector is used to detect the reflected electromagnetic energy from the tissue through a second optical pathway as real-time images. A macro-to-micro lens 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 is used to filter the reflected electromagnetic energy before it reaches the image detector. Furthermore, the endoscope includes a flexible shaft. The distal end of the shaft includes a spread and spot means to spread and spot the electromagnetic energy at the tissue. A processing means is also included for processing the detected images.
