Problems solved by technology

The static display has high requirements on the control accuracy of the laser beam position, and the high resolution requires smaller volume pixels. The two laser beams must accurately intersect at the predetermined position. However, the static volume display based on the TFTS principle needs to meet the requirements of the two laser beams. overlap, so the volume pixel cannot be too small, otherwise the two laser beams are difficult to intersect, which reduces the resolution of the display

Embodiment 1

[0026] Polished six sides 100mmx100mmx1000mm 3 The transparent borosilicate glass-ceramic containing β-BBO nanocrystals is used as a display body, irradiated with focused 900nm, 1082nm and 1224nm Q-switched nanosecond lasers, respectively producing blue, green, and blue near the focus of the laser focus. Red luminescence (frequency doubling scattered light), through the computer-controlled scanning system, forms a three-dimensional three-dimensional color display inside the glass.

Embodiment 2

[0028] Polished six sides 100mmx100mmx1000mm 3 The transparent polymethyl methacrylate containing KTP nanocrystals is used as a display body, irradiated with focused 960nm, 1080nm and 1240nm Q-switched nanosecond lasers, respectively producing blue, green and red luminescence near the focus of the laser focus (frequency doubling scattered light), through the computer-controlled scanning system, a three-dimensional three-dimensional color display is formed inside the glass.

Embodiment 3

[0030] Polished six sides 100mmx100mmx1000mm 3 The transparent silicate glass-ceramic containing LN nanocrystals is used as a display body, and the focused 950nm, 1032nm and 1260nm mode-locked femtosecond lasers are irradiated, and blue, green and red luminescence are produced near the focus of the laser focus respectively. (frequency doubling scattered light), through the computer-controlled scanning system, a three-dimensional three-dimensional color display is formed inside the glass.

Abstract

The invention discloses a method for forming a three-dimensional color display inside a transparent medium, which uses a transparent medium containing second-order nonlinear optical microcrystals of 1 nanometer to 1000 nanometers as the display body, and uses red, green and blue primary colors corresponding to the two-dimensional visible light. Infrared laser with double wavelength scans the display body, and the computer controls the scanning speed and laser focus position to form a three-dimensional color display inside the transparent medium. The invention has the advantages of simple process, high resolution and no ghost point phenomenon. Compared with the previous three-dimensional color display method, it has obvious advantages in the material preparation process of the display, the resolution of the display system and other comprehensive characteristics.

Description

technical field [0001] The invention relates to a method for forming a three-dimensional color display inside a transparent medium. Background technique [0002] For a long time, people have been looking for a technology that can display images in three-dimensional space. TV is a fairly mature plane display. It uses the principle of electron beam to quickly scan two-dimensional plane to excite and generate fluorescence to display images. The observer can only observe the image in a certain area facing the screen, and cannot obtain any depth information about the image. information. The three-dimensional display is not affected by the position of the observer, and the observer can observe 360° around the display body. And the amount of information that can be expressed by three-dimensional display far exceeds that of plane display, and it can instantly display the dynamic information of any part of any angle of an object. These advantages make the three-dimensional display...
