20100171921 | LIQUID CRYSTAL DISPLAY - A liquid crystal display (LCD) includes two glass substrates, a liquid crystal unit formed by sandwiching a liquid crystal layer between the two glass substrates, a first polarizing film, and a second polarizing film. In another example, the LCD further includes a diffuse reflective film formed on the other side of the second polarizing film. In another example, the second polarizing film is replaced by a reflective film. The liquid crystal layer is composed of an antiferroelectric (including intermediate antiferroelectric) smectic liquid crystal material, and a birefringence of the liquid crystal layer changes along with an electric field applied to the liquid crystal layer. | 07-08-2010 |

20110074659 | HIGH SPEED OPTICAL SHUTTER, METHOD OF OPERATING THE SAME AND APPARATUS INCLUDING THE SAME - A high speed optical shutter, a method of operating the high speed optical shutter, and an optical apparatus including the high speed optical shutter. The optical shutter includes a transparent electro-optical medium in an active solid state having a total internal reflection surface on which an angle of total internal reflection is changed by an external action. The transparent electro-optical medium may be a prism or a prism array whose angle of total internal reflection is changed by the external action. An incident light path changing unit may be further arranged in front of the transparent electro-optical medium. Also, a light path changing unit may be further arranged so as to allow light passing through the electro-optical medium to be perpendicularly incident on an incidence target object. | 03-31-2011 |
20120147143 | OPTICAL SYSTEM HAVING INTEGRATED ILLUMINATION AND IMAGING OPTICAL SYSTEMS, AND 3D IMAGE ACQUISITION APPARATUS INCLUDING THE OPTICAL SYSTEM - An optical system including integrated illumination and imaging optical systems, and a 3-dimensional (3D) image acquisition apparatus including the optical system. In the optical system of the 3D image acquisition apparatus, the illumination optical system and the imaging optical system are integrated to have a coaxial optical path. Accordingly, there is no parallax between the illumination optical system and the imaging optical system, so that depth information about an object acquired using illumination light may reflect actual distances between the object and the 3D image acquisition apparatus. Consequently, the depth information about the object may be more precise. The zero parallax between the illumination optical system and the imaging optical system may improve utilization efficiency of the illumination light. As a result, a greater amount of light may be incident on the 3D image acquisition apparatus, which ensures to acquire further precise depth information about the object. | 06-14-2012 |

20090116119 | COMPACT ZOOM LENS - Provided is a zoom lens. The zoom lens includes a first lens group with a positive refractive power, a second lens group with a negative refractive power, a third lens group with a positive refractive power, a fourth lens group with a negative refractive power, and a fifth lens group with a positive refractive power. The first through fifth lens groups are sequentially arranged toward an image side from an object side, and the second, fourth, and fifth lens groups move long the optical axis during zooming. | 05-07-2009 |
