摘要： In a reproducing apparatus adapted to reproduce data recorded on a holographic recording medium, a reference light generator generates reference light for illuminating the holographic recording medium, and a coherent light generator generates coherent light having an intensity greater than the absolute value of a minimum amplitude of a reproduced image and having a phase equal to the phase of the reproduced image. An image signal acquisition unit senses the reproduced image produced by illuminating the holographic recording medium with the reference light and the coherent light, and acquires an image signal based on the reproduced image. A square root calculation unit calculates the square root of each of values constituting the image signal. A removal unit removes the component of the coherent light from the calculated square root, whereby the data recorded on the holographic recording medium is correctly reproduced.

摘要： A hologram reproducing apparatus includes a reference-light spatial-light modulating section that displays a reference light pattern for generating reference light, an image sensor that has pixels arrayed two-dimensionally that receive diffractive light generated by irradiating the reference light on a hologram recording medium, and a control unit that processes an electric signal from the image sensor and reproduces recording data. The control unit detects a predetermined area electric signal, detects a hologram electric signal, subtracts the predetermined area electric signal from the hologram electric signal to obtain a reproduced signal after noise reduction, and reproduces the recording data from the reproduced signal after noise reduction.
