A device for measuring strain and volume of a soil sample including an enclosure adapted to receive a soil sample within another enclosure. A base adapted to hold the sample enclosure. The device also has a plurality of moveable arms located between the enclosures which may be a spaced distance apart and adapted to move around the sample. Cameras as included on the arms.

The present technology relates to an optical element and an optical device that enable resolution of a light image to be increased at a position according to the position of the light image to be detected in an optical element that forms an image without a lens.

The optical element includes an optical element plate that includes, in part, a light transmission part forming a light image of an object by light from the object, the light having passed through a transparent zone that transmits light, and that blocks light in a portion other than the transparent zone, in which the transparent zone is formed such that resolution of a light image formed in a direction different from a normal direction of a plate surface of the optical element plate with respect to the light transmission part is higher than resolution of a light image formed in the normal direction.
