Endoscope for depth data acquisition in e.g. medical area, has modulation unit controlling light source based on modulation data so that source transmits modulated light signal and evaluation unit evaluating signal to estimate depth data

摘要

The endoscope has a light source (102), and light guide optics (104, 106) to receive and to feed light that is received from a light exit (118) to a tip. A sensor (108) receives light that is transmitted from another exit (114) and generates a sensor signal representing the received light. A modulation unit (110) controls the source based on modulation information in such a manner that the source transmits a modulated light signal. An evaluation unit (112) e.g. digital signal processor (DSP), connected with the sensor evaluates the sensor signal to compute depth data. An independent claim is also included for a method for the acquisition of depth data with an endoscope.
