摘要： An uneven-surface data detection apparatus, includes a transparent plate having an uneven-surface contact portion against which an uneven surface to be detected is pressed. A light source illuminates the uneven-surface contact portion through the transparent plate. An uneven-surface image drawing out optical element draws out the light reflected on the uneven-surface contact portion of the transparent plate. A detector detects the light drawn out from the transparent plate by the optical element.Light reflected by a projection-facing portion of the uneven surface contact portion to be introduced into the detector diverges from a propagation direction of light reflected by a recess-facing portion of the uneven surface contact portion. The optical element is arranged to guide the light reflected by the projection-facing portion into the detector.

摘要： An apparatus used in fingerprint identification for extracting minutia data from fingerprint image data. An optical sensor unit optically produces a sequence of fingerprint image data during a single operation of pressing a fingerpad onto an inspection plate in a direction substantially transverse to the plate and with increasing pressure over a time interval. A data storing unit stores the produced fingerprint image data in the form of a sequence of fingerprint image data obtained during the single operation of pressing the fingerpad onto the inspection plate. The stored fingerprint image data is utilizable for identification of the fingerprint.

摘要： An uneven surface data detection apparatus for detecting an uneven surface, such as a human finger, having projected portions and recessed portions. A transparent base having upper and lower surfaces and an upper surface defining an uneven surface contact portion is provided, and a light is incident on the uneven surface so that the light derived from the recess portions enters to the transparent base and comes out thereof. However, a part of the light derived from the projected portions is totally reflected at least one time by the lower opposite surface and focussing lens is integrally formed on the transparent base so that the totally reflected light is drawn out of transparent base and enters to an image sensor.

摘要： Light-beam scanning apparatus mainly used for a bar-code reader in a point-of-sale system to identify sold articles. The apparatus includes a light-beam emitting device, a hologram disk having a plurality of hologram segments with different diffraction characteristics mounted along its circumference and being rotated at a predetermined speed, and a deflecting device for directing the emitted light beam from the light-beam emitting device to one side of the hologram disk in a first direction. The scanning apparatus has a first mirror group including a plurality of mirrors placed in a second direction corresponding to the other side of the hologram disk, each of which mirrors is arranged to receive a diffracted light beam from a corresponding hologram segment, and a second mirror group including a plurality of mirrors, each of which mirrors is placed to receive a light beam reflected by a corresponding mirror of the first mirror group and to reflect the incident light beam to a predetermined space positioned in the first direction where an article attached with a bar-code label is moved. In the apparatus, a light path from the other side of the hologram disk to the predetermined space has a predetermined length to form a predetermined scanning light pattern in the space.

摘要： A high precision laser beam scanner is provided which is able to shape a beam generated by a laser, suppress the influence of jitter of a scanning beam due to mode hopping of a semiconductor laser, and reduce aberration of the scanning beam. A beam source generates a semiconductor laser beam, which is diffracted by a rotary hologram, forming a scanning beam on a surface to be scanned. An aberration correcting stationary hologram is disposed between the beam source and the rotary hologram. The stationary hologram is constructed with an object wave and a reference wave, which interfere on a stationary hologram substrate subject so that an aberration of the scanning beam on the surface to be scanned shall be corrected. The object wave is a spherical wave which has an aberration, a wave length shorter than that of the semiconductor laser beam, and an incident angle which is not vertical but is inclined with respect to the stationary hologram substrate. A method for fabricating the laser beam scanner is also provided.
