Apparatus and method for endoscopic 3D data collection

An apparatus for endoscopic 3D data collection having:

• light-generating means for generating at least one modulated measuring beam,
• light-transmitting means for transmitting the measuring beam onward to an area to be observed, where the light-transmitting means includes an illuminating lens that can be applied endoscopically,
• light-imaging means for imaging a signal beam from the area to be observed onto at least one phase-sensitive image sensor, which comprises a plurality of pixels, where the light-imaging means includes an imaging lens that can be applied endoscopically,
• where the illuminating lens and the imaging lens are positioned in a shaft that can be applied endoscopically, and
• control and evaluation means for controlling the light-generating means, for powering the phase-sensitive image sensor, and for evaluating data supplied by the phase-sensitive image sensor for generating 3D data,
• where at least one additional image sensor is provided and the light-imaging means includes at least one of a beam-splitter and an optical switch, distinguished in that
• the image sensors have different formats, and
• at least one adaptive lens is provided for adapting fields of vision of the phase-sensitive image sensor and the additional image sensor.
