The Applications of a Liquid Crystal Panel for the 15 Gbyte Optical Disk Systems

Abstract: A numerical code has been developed to calculate the loading of a cavity loop antenna in threedimensional geometry. The loading of the cavity is calculated for fast wave and ion Bernstein wave coupling and compared with the loading of a conventional loop antenna. For fast waves, the cavity loading increases with increasing edge density, while the conventional loop loading is less sensitive to the edge density but shows a slight decrease of loading because of a steeper density gradient. For ion Bernstein waves,… Show more

“…[22][23][24][25][26] To solve the aforementioned problems, we have developed transmissive liquid crystal devices for the correction of a specific spherical aberration. These devices consist of liquid-crystal cells (LCCs) wherein a layer of liquid crystal molecules is sandwiched by a pair of glass substrates equipped with transparent electrodes.…”

“…In these systems, the recording substrate is predominantly isotropic, so aberrations can be predicted from the focusing depth, obviating the need for direct aberration measurement. LC devices have been used in single or dual recording layer systems to correct spherical aberration due to the disc thickness and coma caused by disc tilt (Ohtaki et al 1999;Somalingam et al 2004;Knittel et al 2005). The aberrations become more significant in three-dimensional storage where focusing depths are much larger.…”

“…[7][8][9][10][11] These liquid-crystal devices consist of liquid-crystal cells (LCCs), wherein a layer of liquid-crystal molecules is sandwiched between a pair of glass substrates equipped with transparent electrodes. 12 These liquidcrystal molecules exhibit directional refractive-index anisotropy that is electrically controllable; therefore, a segmented pattern of a transparent electrode generates a phase distribution that corresponds to the segmented pattern in the wavefront of penetrating light.…”
