Abstract: A three-dimensional measurement device includes a plurality of light source units configured to irradiate the object to be measured with measurement light having predetermined patterns, an image capture unit configured to capture an image of the object to be measured which is irradiated with the measurement light, and a measurement unit configured to measure a three-dimensional shape of the object to be measured based on results of image capture performed by the image capture unit. The predetermined patterns of the measurement light include stripe patterns, respectively. The stripe patterns radiated from the plurality of light source units have respective patterns different from each other. The plurality of light source units are arrayed in a direction parallel to stripes in the stripe patterns. The measurement unit measures the three-dimensional shape of the object to be measured based on a three-dimensional shape measurement method using the stripe pattern.

Abstract: A smell sensor includes an ion sensor having a sensitive film, a substance adsorption film disposed on the sensitive film and configured to adsorb a smell substance to be detected, and an electrode configured to apply a reference voltage to the substance adsorption film. The substance adsorption film is in a state of releasing a proton in response to absorbing the smell substance.
