Scanning method of an electromagnetic wave, the video projection apparatus and an image acquisition device

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic scanning method that can determine a frequency suitable for picture projection, and provide a picture projection device and an image acquisition device.;SOLUTION: When an electromagnetic wave is scanned in a first deflection direction x and a second deflection direction y that are vibrating and independent, a deflection reflector 2 for changing the direction of the electromagnetic wave sets a first deflection frequency f_x at a value obtained by the expression, where the resolution in the second deflection direction is represented as Y and a frame rate at which the scanning of the entire scan area is completed is represented as F.;COPYRIGHT: (C)2013,JPO&INPIT
