Abstract: A blurless image capturing system sequentially acquires images with little blur, even in a situation where a camera moves. An image capturing camera unit and a mirror unit are both capable of continuous movement in at least a one-dimensional direction. The image capturing camera unit acquires an image of a physical object present within an object region by directing line of sight direction towards the object region by means of the mirror unit. The mirror body changes the line of sight from the image capturing camera unit. The drive unit changes an angle of the mirror body in a given angular velocity in accordance with movement of the image capturing camera unit and the mirror body In this way it is possible to keep the line of sight from the image capturing camera unit directed towards a physical object for a given time. The drive unit directs the line of sight from the image capturing camera unit towards another object region by driving the mirror body. The control unit controls operation of the drive unit.

Abstract: Controlling the position of a light beam uses a dielectric elastomer itself as an optical element. By controlling the position of a light beam, it is possible to maintain high resolution, even where an object is at a distance. The main body is constituted by a dielectric elastomer. This dielectric elastomer is made substantially transparent to a light beam that is an object of control. The dielectric elastomer is made to have a refractive index that is different than a refractive index of a medium that exists around the main body and that the light beam will pass through. The feed section is configured to cause a change in the thickness of the main body by applying a voltage to the main body.

Abstract: A substance identification device, a substance identification method and a substance identification program that can identify substances with high accuracy by means of light are provided. A substance identification device 10 includes a setting unit 11 that sets an irradiation condition of excitation light, an irradiation unit 12 that irradiates an object 100 with the excitation light under the irradiation condition, a measurement unit 13 that measures emission data for delayed fluorescence or phosphorescence of the object 100 which occurs in response to the irradiation with the excitation light, and an identification unit 15 that identifies a substance constituting the object based on the emission data and emission data for delayed fluorescence or phosphorescence which are measured when a plurality of substances are each irradiated with the excitation light under the irradiation condition.
