Conventional holographic original technologies:
1D grating
The grating structure features simple linear gratings at sub-micron level. The grating causes diffraction and reflects rainbow spectrums when white light passes through.
2D grating
The grating structure consists of vertical and horizontal gratings. As a result, we can see rainbow spectrum in either direction.
2D/3D multi-layers
This is the most popular technique used in the field of conventional holography. The characteristic is to show multiple 2-dimentional images at different layers. This technique creates a sense of depth and pseudo 3D effect.
True 3D image
In addition to color shift, the most unique characteristic of a hologram is the 3D effect. We can make true 3D hologram image by recording a 3D model in the hologram. Holograms made with this technique are difficult to duplicate.
Dot-matrix
This technique uses two laser beams to create interfering grating, and uses computer to encode and decode grating data to generate the image. Now K Laser can provide many resolutions of dot-matrix images, with the maximum resolution of 1000 dpi.
Real color
Through using computer aided analyzing system, we can convert the pixels of a color picture into corresponding proper grating. With this technique, we can produce a hologram image that looks of the same color as the original picture in a certain angle.
Multi-channel
Employing light guide theory, we are able to make one image visible in a defined area. We advance the technique to encode multiple images in a small area, and that makes our hologram harder to duplicate.
Advanced computer generated origination technique:
One-step stereogram
We use computer software to collect the image information and transfer the information to an LCD panel to produce the object beam. An optical system is built to guide the laser beam. Then the guided object beam and the reference beam are used to record images onto a photo-resistant plate. Using this technique, we can reproduce full colors and 3D images on a hologram master.
Matrix Writer
Matrix Writer® is a newly proprietary system developed by K Laser Technology. The system uses laser direct writing method to record the holographic fringes and waves on a photo-resistant plate to generate the grating.
With this system, we can create fine, colorful virtual 3D images.
E-beam technology
This technology uses electron beam to record the profile of the holographic fringe on a photo-resistant plate. This technology features high resolution and high precision. Therefore, we can engrave fine images with rich colors using this technology. |
