    摘要： An optical design method attempting facilitation of optical design of a configuration including a metalens. The optical design method includes a setting step, a first calculating step, a first identifying step, a second calculating step, a second identifying step, and a designing step. The first calculating step calculates first phase data indicating a relation of a phase to a shape of a meta-atom based on a preliminarily set first wavelength. The first identifying step calculates a first phase pattern from a first step pattern and identifies a fine pattern indicating the shape of the meta-atom corresponding to the first phase pattern by referring to the first phase data. The second calculating step calculates second phase data different from the first phase data based on a preliminarily set second wavelength different from the first wavelength.

    摘要： In classifying images by machine learning, provided are an image classification method, device, and program for classifying the image from which the feature difference is hardly detected, in particular, classifying the interference fringe image of tear fluid layer by the dry eye types. The method includes a step of acquiring a feature value from an interference fringe image of tear fluid layer for learning, a step of constructing a model for classifying an image from the feature value acquired from the interference fringe image of tear fluid layer for learning, a step of acquiring the feature value from an interference fringe image of tear fluid layer for testing, and a step of performing classification processing for classifying the interference fringe image of tear fluid layer for testing by types of dry eye using the model and the feature value acquired from the interference fringe image of tear fluid layer.

    摘要： The finger supporter is disclosed. The finger supporter includes: a first anchor portion 2 that is formed at an upper end 10a of a tubular fabric and causes the tubular fabric to be fastened to a forearm wrist portion of a wearer; a second anchor portion 3 that is formed to continue two points of a circling portion on the other end side of the tubular fabric and forms the circling portion into two opening portions 12a and 12b with different sizes; and a first support portion 4 that couples the second anchor portion 3 and the first anchor portion 2 and supports any one finger inserted into the smaller opening portion 12a from among five fingers.
