Abstract:
The optical tomographic image acquisition apparatus is based on FD-OCT. A detection unit 50A which detects interference light includes a lens 51, a reflection type diffraction grating 52A, a deflection unit 53, a lens 54), and a light receiving unit 55. The interference light collimated by the lens 51 is divided by the reflection type diffraction grating 52A. Light of each wavelength is output in a different direction according to the wavelength, deflected by the deflection unit 53, and focused on a light receiving surface of the light receiving unit 55 by the lens 54. The optical tomographic image of the object is acquired based on a correspondence relationship between a light radiation position for the object and a deflection angle by the deflection unit 53 and on optical power distribution detected by the light receiving unit 55.

Abstract:
An image registration server stores encryption keys of respective ones of a plurality of client terminals. Image data is encrypted by the image registration server using the encryption key corresponding to the client terminal to which the image data is applied. The encrypted image data is applied to the client terminal via a server. The client terminal has a decryption key stored within so that only a client terminal that is duly authorized can decrypt encrypted image data. Other client terminals that are not duly authorized cannot decode the image data. This makes it possible to prevent unlawful use of image data even if the image data has been intercepted.
Abstract:
A vehicle speed calculating section calculates the vehicle velocity by integration of a forward and reverse acceleration of a vehicle. A first deforming speed calculating section calculates a first deforming speed by integration of acceleration from a first acceleration sensor. A second deforming speed calculating section calculates a second deforming speed by integration of acceleration from a second acceleration sensor. A first deforming speed correcting section subtracts a vehicle speed from the first deforming speed and outputs it to a determining section. A second deforming speed correcting section subtracts the vehicle speed from the second deforming speed and outputs it to the determining section. In the determining section, the collision object determination is made on the basis of the corrected deforming speed.
Abstract:
In the development of a Web application system, each of the components of the servlet, JSP, and Bean is define in a one-to-one relationship corresponding to each screen image, thereby making the relationship among each of the components clear. A component table generating unit is provided for generating the definition of each component as a component table from screen design. Also provided is an automatic code generating unit for automatically generating the code of servlet, JSP, and Bean using the component table and the information of the design document. This facilitates the development and alleviates the burden on developers or programmers.
Abstract:
The light which is input from an optical fiber to a first port is output to an optical path. The light which is input from the optical path to a half mirror is branched into two, and is output to the optical paths. The light which is output to the optical path reaches to and is reflected from a first reflecting mirror, and returns to the half mirror by an optical path. The light which is input to the half mirror by the optical path is branched into two, and is output to the optical paths. The light which is output to the optical path reaches to and is reflected from a second reflecting mirror, and returns to the half mirror by an optical path. The light which is input to the half mirror by the optical path is branched into two, and is output to the optical paths. The light which is output to the optical path is output from a second port to an optical fiber, and the light which is output to the optical path is output from a third port to an optical fiber.
Abstract:
It is the object of the present invention to provide an optical element for controlling the polarization state spatially by using a liquid crystal and a method for manufacturing the same, and to provide an optical apparatus for correcting the polarization state in conformity with a particular purpose and method for manufacturing the same. The optical element for controlling the polarization state of light spatially by modifying directions of orientation of liquid crystal molecules caused by an oriented film and the optical apparatus by the use of the optical element are described. Orientation which is realized in the aforesaid oriented film for liquid crystal molecules is controlled by light irradiation with ultraviolet light etc. In irradiation, used is either of two methods: one method in which light irradiation is performed while the polarization state is being changed by using masks; the other method in which light irradiation is performed while the oriented film is being moved relative to the light irradiating means.

Abstract:
Disclosed is a program development support system so adapted as to integrally manage a variety of information necessary for the development of a program by creating necessary links between information such as source programs to be employed for the development of the program, program parts, tools, specifications, handling persons and so on, by managing such information as resource information and by retaining attribute information of the links. The program development support system has a store means for storing program development information on the development of a program; a create means for creating attribute information on an attribute of the program development information and link information between each of the program development information; a management means for managing the program development information, the attribute information created by the create means and the link information created thereby each as one resource for the development of the program by providing the resource with a unique number; and a system-structuring element creating means for creating a system-structuring element from the resource by using the link information.
Abstract:
A light exposure and illuminating device in which an outgoing light of an exposure light source is supplied to a light exposure section for illuminating an object to be exposed to light. A moving scattering medium scatters a laser beam outgoing from a laser light source. A light condenser lens condenses the laser beam scattered by the moving scattering medium to a laser beam of a suitable diameter. A plurality of prisms condense the laser light condensed by the light condenser lens as a rectangle of a suitable size on an incident surface of a fly-eye lens. The fly-eye lens uniforms the intensity distribution of the laser beam in cooperation with a folding lens. Another condenser lens radiates the laser beam uniformed in intensity distribution by the fly-eye lens and the firstly-stated condenser lens as a exposure illuminating light on a mask for light exposure on which a light exposure pattern is pre-formed. With the present light exposure illuminating device, a small-sized inexpensive light source may be realized. In addition, the illuminating light is uniform and free of fluctuations or speckles, while a high light source utilization efficiency may be achieved.
