Spectroscopic sensor for measuring omnidirectional area in two-dimensional plane

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper describes a spectroscopic sensor for measuring a wavelength of the light from objects in two-dimensional omnidirectional area. I developed the spectroscopic sensor, in which vertical slits, a horizontal slit, a cylindrical reflective grating ...

Bio-Inspired Wide-Angle Broad-Spectrum Cylindrical Lens Based on Reflections from Micro-Mirror Array on a Cylindrical Elastomeric Membrane

open access: yesMicromachines, 2014
We present a wide-angle, broad-spectrum cylindrical lens based on reflections from an array of three-dimensional, high-aspect-ratio micro-mirrors fabricated on a cylindrical elastomeric substrate, functionally inspired by natural reflecting superposition

Introducing the Patterson Cylindrical Projection

open access: yesCartographic Perspectives, 2015
The Patterson cylindrical, a new projection designed for general-purpose mapmaking, is an alternative to other cylindrical projections. It is positioned between the Plate Carrée projection, which has a 1:2 aspect ratio, and the Miller 1 projection, which excessively exaggerates the size of polar areas.

2D-TDOA passive location based on geodetic longitude and latitude

open access: yesTongxin xuebao, 2019
Because of the surface of the earth is not a plane,there may be some errors in the conventional ultra-short wave passive TDOA location method using plane coordinates.In order to use the geodetic longitude and latitude coordinates directly for TDOA ...
