  • Publication number: 20240142696
    Abstract: An objective of the present invention is to provide a mode conversion device capable of designing any coupling efficiency and full width at half maximum, and a design method therefor. According to the present invention, a mode conversion device includes a long period grating at a core of an optical fiber through which light is able to propagate in at least two propagation modes. The long period grating satisfies a relationship of Expression C1, where a full width at half maximum FWHM is a wavelength band in which the coupling efficiency is a half of coupling efficiency of mode conversion at a center wavelength, C is coupling efficiency, Lc is a complete coupling length, Lg is a grating length, ? is a grating pitch, and ?? is a propagation constant difference between the two propagation modes at the center wavelength of a mode conversion target.

  • Publication number: 20240104914
    Abstract: A learning model generates a plurality of prototype vectors and generates an integrated similarity vector that indicates similarity between an input image and each prototype for a plurality of prototypes in accordance with similarity between one prototype vector and each pixel vector in a feature map acquired from an CNN. An image processing apparatus obtains prototype belongingness (distributed prototype belongingness) for each image by distributing prototype belongingness of a belonged prototype of each class to each of two or more images that belong to one class. Then, the learning model is subjected to machine learning in accordance with the distributed prototype belongingness of each prototype vector for each image so that each prototype vector is brought closer to any pixel vector in the feature map corresponding to each image.

  • Patent number: 10339811
    Abstract: A technology for displaying images on a displaying apparatus mounted on a vehicle is provided. In response to a predetermined instruction signal, synthetic images viewed from a virtual viewpoint around and above the periphery of the vehicle are generated based on a plurality of images acquired from a plurality of cameras for capturing the periphery of the vehicle. The plurality of synthetic images, in which a position of a viewpoint moves sequentially varies such that the synthetic images move in a circle around the vehicle, are sequentially output to the displaying apparatus. Accordingly, the user monitors the entire circumference of the vehicle from the viewpoint where the user sees the vehicle in front of user's eyes, so that the user can intuitively recognize the positional relation between the vehicle and an obstacle from one screen.
