MEDICAL OBSERVATION SYSTEM, MEDICAL OBSERVATION DEVICE, AND MEDICAL OBSERVATION DEVICE DRIVING METHOD

摘要

A medical observation system (2, 3) is provided with: a light source (223) that illuminates an affected area; a separation optical system (213) that separates light from the affected area into a plurality of polarized light beams, the polarization directions of which are different from each other; a detection unit (313) that individually detects the plurality of polarized light beams; a calculation unit (305) that individually calculates speckle contrasts on the basis of results of detections of the plurality of polarized light beams; and a processing unit (303) that, on the basis of at least any one of results of calculations of the speckle contrasts respectively corresponding to the plurality of polarized light beams, executes a process for observation of the affected area.
