Title:
LIGHT BEAM SCANNER, IMAGE DISPLAY UNIT AND LIGHT BEAM SCANNING METHOD
Document Type and Number:
Japanese Patent JP2001117032
Kind Code:
A
Abstract:
To reduce driving energy required for scanning and to enhance scanning speed.
An image is formed by performing deflected scanning of writing light 10 outputted from a light beam output device 3e according to preset conditions by a deflected condenser 3f constituted of a concave lens and a convex lens in the direction of X axis, holding spot diameter of the writing light 10 to condense on an image display panel 2 as constant for change of length of an optical path of the writing light 10 from the deflected condenser 3f to the image display panel 2 and irradiating the writing light 10 on the image display panel 2 while transferring mirror 3a for scanning to reflect the writing light 10 in the direction of Y axis.
