Title:
OBSERVATION DEVICE, OBSERVATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/044527
Kind Code:
A1
Abstract:
An observation device according to one embodiment of the present art includes a first polarization unit, a second polarization unit, a rotation control unit, and a calculation unit. The first polarization unit emits polarized light having a first polarization direction to a biological tissue. The second polarization unit extracts, from reflected light that is the polarized light reflected from the biological tissue, a polarized component having a second polarization direction intersecting the first polarization direction. The rotation control unit rotates the first and second polarization directions such that the angle of intersection of the first and second polarization directions is maintained. The calculation unit calculates biological tissue information on the biological tissue on the basis of a change in intensity of the polarized component having the second polarization direction in response to the rotation operation by the rotation control unit.
