Abstract: [Object] An observation device according to an embodiment of the present technology includes an emission unit, an imaging unit, a polarization control unit, and a calculation unit. The emission unit sequentially emits a plurality of polarization light beams of mutually different polarization directions to a biological tissue. The imaging unit includes a plurality of pixels capable of outputting pixel signals respectively. The polarization control unit considers a predetermined number of pixels of the plurality of pixels as one group and causes mutually different polarization components of reflection light beams reflected by the biological tissue to be respectively incident upon respective ones of the predetermined number of pixels included in the one group. The calculation unit calculates biological tissue information regarding the biological tissue on the basis of the pixel signals output from the respective ones of the predetermined number of pixels.

Abstract: An imaging device according to an embodiment of the present technology includes a first polarization section, a second polarization section, a rotation control section, and a generation section. The first polarization section irradiates a body tissue with polarization light of a first polarization direction. The second polarization section extracts a polarization component of a second polarization direction that intersects with the first polarization direction, from beams of reflection light that are the polarization light reflected by the body tissue. The rotation control section that rotates each of the first polarization direction and the second polarization direction while maintaining an intersection angle between the first polarization direction and the second polarization direction. The generation section that generates an image signal of the body tissue on the basis of the polarization component of the reflection light extracted by the second polarization section in accordance with rotation operation performed by the rotation control section.
