摘要： A method of producing a hologram element is disclosed that is able to prevent spread of a polymerization reaction and light leakage during exposure with interference light, and improve productivity in mass production. The hologram element is for transmitting, reflecting, diffracting, or scattering incident light, and includes a pair of substrates, an isolation member between the substrates that forms an isolated region, and a photo-sensitive recording material sealed in the isolated region. The hologram element includes a periodic structure formed by exposing the recording material to interference light. The interference light is generated by two or more light beams, or by using a master hologram. The recording material is formed from a composite material including a polymerized polymer or a polymerized liquid crystal. The periodic structure is formed by exposing the recording material to the interference light to induce the polymerization reaction and phase separation in the composite material.

摘要： In a laser printer or the like, for the purpose of increasing a recording speed, the number of revolutions of a laser beam deflector is not increased but a plurality of scanning lines are simultaneously scanned. To this end, a plurality of laser beams with an angle of incidence slightly varied are simultaneously incident upon one and the same laser beam deflector. In the event that places for installation of a plurality of light sources are hindered each other by other light sources, light sources different in polarization surface from each other are used, and when beams are combined by means of a polarization beam combiner, a combined beam which is different in angle of emergence through a fine angle each other can be obtained without loss of light.

摘要： A velocity detecting device includes an image-pattern acquiring unit that includes a laser light source and an area sensor that acquires a one-dimensional or a two-dimensional image. The image-pattern acquiring unit includes a lens between a moving member and the area sensor, irradiates a beam emitted from the laser light source to the moving member to make a scattering light of the moving member scattered from the moving member on the area sensor by using the lens, and acquires an image pattern at a predetermined time interval in association with movement of the moving member. A velocity calculating unit calculates the velocity of the moving member by computing the image pattern acquired by the image-pattern acquiring unit. The lens is a reduced optical system that projects a reduced object onto the area sensor.
