Abstract: A display device comprises a projection device projecting a display image, an aerial imaging element, and a distribution mechanism in which distribution units are arranged at a given interval. An interval between the distribution units is determined according to a relationship between a number of view point pixels constituting a pixel unit, a number of pixel units, a distance from the pixel unit at a center to the pixel unit at an edge, a distance from a distribution unit at a center to the distribution unit at an edge, a pitch of the view point pixel, an angle of light from the pixel unit at the center emitted to the distribution unit, and an angle of the emitted light, an angle of light from the pixel unit at the edge emitted to the distribution unit, and an angle of the emitted light, a distance between the projection device and the distribution units, a refractive index of the distribution mechanism, a distance between the real image and an optimal viewing position for a viewer, and a projection width.

Abstract: A tactile presentation device includes a touch surface fixed in orientation, an actuator configured to vibrate the touch surface along one axis within the plane of the touch surface, and a controller configured to control vibration of the actuator along the one axis to present tactile stimulus to a finger in contact with the touch surface. The controller is configured to control the actuator in such a manner that direction to start vibration for presenting tactile stimulus to the finger is within a range from minus 43° to plus 43° with respect to a direction of gravity projected on the touch surface or the opposite direction thereof.

Abstract: A microdevice includes: a microchannel to which a measurement target solution containing a measurement target substance is introduced; an antibody being fixed to at least one sidewall surface of the microchannel and specifically binding to the measurement target substance; a fluorescence-labeled derivative being specifically bound to the antibody and being acquired by fluorescence-labeling the measurement target substance; and a light blocker blocking excitation light exciting fluorescent light radiated by the fluorescence-labeled derivative. The measurement target substance and the fluorescence-labeled derivative specifically bind to the antibody in a competitive manner, and the antibody is fixed to the sidewall surface of the microchannel in a state of specifically binding to the fluorescence-labeled derivative. The light blocker blocks the excitation light entering the fluorescence-labeled derivative specifically binding to the antibody.

Abstract: A stereoscopic display apparatus includes: a projector of a planar shape that projects images by using light acquired by dividing light rays; an optical device of a planar shape that outputs incident light incident from a first face from a second face; and a supporting unit that supports at least one of the projector and the optical device to be in a first state or a second state in an orthogonal three-dimensional coordinate system. The optical device outputs incident light incident from a first point on a projection surface of the projector to a second point having plane symmetry with respect to a plane of the optical device as a reference.

Abstract: An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.

Abstract: A fluorescence polarization immunoassay that uses a fluorescent labeling substance in which a single domain antibody is labeled with a fluorescent dye. A fluorescent labeling substance obtained by labeling a single domain antibody, such as a VHH antibody or a vNAR antibody, having a binding ability to a target substance with a fluorescent dye is used. The fluorescence polarization immunoassay includes a binding step for binding the fluorescent labeling substance to a target substance; and a measuring step for measuring a change in the fluorescence polarization of the fluorescent labeling substance to which the target substance is bound.
