A polarization converter having a planar light guide element is disclosed, in which at least one of front and rear surfaces thereof defines a light emission surface and one edge surface defines an initial edge surface for unpolarized light, and at least one corrugated reflection boundary surface being provided in the light guide element. The reflection boundary surface is defined by at least two adjacent optical media having different refractive indexes. The normal vectors of each surface are within a normal surface, so that light incident upon the initial edge surface can be emitted from the light emission surface. A lighting device for an LCD panel using a polarization converter is also disclosed.

A real image finder system of a camera has an objective lens, an eyepiece lens and deflecting system. The deflecting system includes an erecting system positioned between the objective lens and the eyepiece lens. The finder system also includes an LCD panel that is located on an image plane of the objective lens with the LCD panel displaying information which is viewed through the eyepiece lens. A first polarizer is positioned between the objective lens and the LCD panel while a second polarizer is positioned between the LCD panel and the eyepiece lens. The first and second polarizers are arranged such that their transmission axes are perpendicular to each other. Further at least one optical component of the deflecting system is located between the first polarizer and the second polarizer.

This invention relates to a means of analyzing the shape of a surface to be measured by generating interference fringes containing a spatial carrier produced by tilting the wavefronts from a reference surface and the surface to be measured, taking several measurements of these interference fringes while varying the optical path length of the reference surface by means of a phase shift device, applying a spatial fringe scan method to the interference fringe data so as to detect the optical path length variation produced by the phase shift device, applying a temporal fringe scan method to this optical path length variation and several interference fringe data so as to analyze the interference fringes, and then subtracting the spatial carrier from the analytical results.

A signal detecting apparatus in an optical disc apparatus having an objective lens which converges light emitted from a light source onto an optical disc and a condenser lens which converges light reflected by the optical disc and transmitted through the objective lens includes first and second light receiving elements, each having a light receiving surface located before or behind a convergence point on which the light reflected from the optical disc is converged when the objective lens is in a focal position. Each of the light receiving surfaces are split into at least four light receiving areas. The signal detecting apparatus also includes a means for calculating a sum of differences of outputs of the light receiving surfaces' inner light receiving areas, calculating a sum of differences of outputs of the light receiving surfaces' outer light receiving areas, and then calculating a difference of the sums of differences, so that a track error signal is output in accordance with the difference of sums of differences calculated by the calculating means.
摘要:
An interferometer for measuring the degree of deformation of an object, wherein alignment detection is facilitated by producing a moire pattern. An image signal data for reference fringes is compounded with interference fringe data that has been used for alignment detection. In generating a moire pattern, the interference fringe image signal data is process using the reference fringe data as a filter, resulting in improvement in visibility of the moire pattern.

To avoid the need for off-line collaboration, a primary user who is attempting to enter data required for computer-based process may, as part of the data entry process, delegate data entry tasks for specific input fields to designated delegate users who are more likely to be knowledgeable about the data to be entered. Data entry operations performed by the primary user are recorded and used to build a transaction model which will enable a server to provide required data input screens to delegate users. Data entered by the delegate users is merged with data entered by the primary user to meet the requirements of the computer-based process.
