摘要:
The present invention relates to an optical recording apparatus, which multiplexes the radiation angles of diffracted beams through the use of a one-dimensional diffractive light modulator at the time of recording data on a holographic recording medium, etc., so that the occurrence of errors associated with a high addressing rate and spatial location for data recording is prevented, thus making a separate correction circuit and an additional device for compensating for errors unnecessary.

The present invention relates to an optical recording apparatus, which converts a one-dimensional signal beam into a two-dimensional signal beam using a scanning mirror at the time of recording data on a holographic recording medium, etc., thus greatly reducing required manufacturing processes when manufacturing a spatial light modulator. The optical recording apparatus includes a light generation and radiation means for generating beams, and dispersing and radiating the beams in two directions. A reference beam radiation means converts radiation angles of reference beams and radiates the reference beams having different angles onto a recording medium. A one-dimensional signal beam generation means diffracts and spatially modulates the beams incident from the light generation and radiation means to generate a one-dimensional signal beam and radiates the one-dimensional signal beam. A two-dimensional signal beam radiation means reflects the one-dimensional signal beam in two directions on the same horizontal plane and radiates a two-dimensional signal beam onto the recording medium.

Disclosed herein is a variable grating diffractive light modulator, which actuates lower reflecting plates of a lower reflecting array by a piezoelectric actuating method, and includes an upper reflecting array that is spaced apart from the lower reflecting array and attached to a lower surface of a substrate that is made of a light transmissive material and covers the lower reflecting array, so that the light modulator reflects incident light transmitted through the substrate and thereby produces diffractive light.

The present invention relates to a scanning apparatus using a light modulator. The scanning apparatus simultaneously and horizontally scans a plurality of diffracted beams, formed by actuating cells turned on/off in response to externally applied drive power, onto a photosensitive member. The scanning apparatus includes a first lens unit for converting a single beam, emitted from a light source, into collimated light, and emitting the collimated light. A light modulation means includes a plurality of actuating cells turned on/off by drive power, and diffracts and modulates the single beam to form a plurality of diffracted beams by on/off operation of the actuating cells. A filtering means selectively allows diffracted beams having at least one predetermined diffraction coefficient, among the plurality of diffracted beams formed by the light modulation means, to pass therethrough. A second lens unit focuses the plurality of diffracted beams selectively passing through the filtering means onto a photosensitive member.

Provided are a microfluidic device and a microfluidic analysis equipment. The microfluidic device includes guides disposed along both edges, a lower plate including a flow path defined between the guides, and a movable upper plate moved along the guides on the lower plate and having a length less than that the flow path. A fluid flow can be simply accurately controlled by adjusting a position of the movable upper plate. As a result, the fluid can sufficiently react in the detection part and the reaction part. Therefore, effective reaction and detection can be realized using only a small amount of fluid, thereby improving sensitivity. In addition, due to the improved sensitivity, a washing process for removing materials that are not consumed in the reaction can be omitted. Also, the movable upper plate can be manually moved using a user's finger.
