“…The system will also be applicable to maskless lithography for fabricating various microstructures such as bio-devices [15,16], micro fluidic devices [17][18][19], micro-lenses [20,21] and others in the future. On the other hand, lithography using LEDs is also watched with keen interest depending on the recent developments of ultra-violet and short visible light LEDs with strong intensities [22,23].…”

A new optical lithography method for fabricating humpbacked pattern arrays was developed. The patterns were printed by adopting intentionally defocused projection exposure under the condition of very low numerical aperture of 0.089. As a resist, approximately 100-µm thick SU-8 (MicroChem) was used, and appropriate defocuses were 1400-2000 µm. When the exposure time and the defocus were changed, curvature radiuses of lens patterns were controllable in a wide range of 70-300 µm. The curvature radii became large when the exposure time was extended, and the defocus was reduced. The patterns will be usable as original molds of lenticular lens arrays. In addition, the patterns will also be usable as temporal lenticular lens arrays as they are, because the SU-8 is almost transparent for visible light.

“…There are many kinds of implementation schemes for autostereoscopic 3D display. For example, some schemes are based on geometrical optics or parallax barrier, and using cylindrical lens or micro lens as the basic principle is also attracting the attention of the researchers [2][3][4][5][6][7][8]. But these schemes can only provide image with limited resolution, and the ghost images and visual fatigue always exist.…”

Autostereoscopic 3D, a kind of display technology, can give people an amazing visual experience. A design of autostereoscopic 3D display based on the polarization gratings is proposed in this paper. The designed system is placed on the outside surface of LCD. Image from two video sources which have parallax, can be alternately displayed on the LCD screen at a rate of 48 frames per second, and owing to polarization gratings, the direction of emergent light of the system can be changed which depends on the handedness of the incident light. By using the unique diffraction characteristics of the polarization gratings and fast response of liquid crystal, the image from two different video sources enters people's left and right eye respectively. Due to the existence of parallax, people can perceive depth of the image. The system is based on the time division multiplexing of LCD pixels, so there is no pixel loss and image with full resolution can be used.
