Abstract
An optical computing device includes an optical modulation element group including optical modulation elements. The optical modulation element group executes first optical computing with respect to a first signal light traveling along an optical path and second optical computing with respect to a second signal light traveling along the optical path in a direction opposite to a traveling direction of the first signal light.
