Abstract: A stereo-endoscope for observation and analysis of an object, comprising a shaft with distal and proximal ends, illuminating means for illuminating the object, and stereoscopic imaging means which transfer light radiated by the object from the distal end to the proximal end. Light of a first imaging channel is fed into a first sensor, and light of a second imaging channel is fed into a second sensor. Both sensors contain mutually different beam splitters, which split the light into four light beams. One light beam from each of the sensors is deflected onto one sensor each; these two sensors are identical. The signals detected there are assembled to form a stereoscopic image. The stereo-endoscope comprises mutually different manipulating means for the other two light beams; by means of suitably-tuned image-processing algorithms, two different monoscopic images containing information complementary to each other and to the stereoscopic image are generated.
