    摘要: A method and device for measuring the tilt in an optical disc drive (1) is disclosed. The optical disc drive (1) comprises two lasers (31, 41) generating two laser beams (32, 42) having mutually different optical characteristics. One of these laser beams (32) is continuously ON, and is used for writing or reading data to or form the disc. The other laser beam (42) is repeatedly switched ON and OFF. Tilt is measured by comparing a normalized error signal (RES(ON)) during the ON-phase (TON) with a normalized error signal (RES(OFF)) during the OFF-phase.

    摘要: A signal processing technique is proposed for compensating for radial to focus crosstalk in an optical storage system including an astigmatic lens (25) and four-quadrant photodetector (26) for generating a focus error signal. A signal processor generates the focus error signal (FESRVO), a tracking error signal (TES) and a central aperture signal (CA) and the proposed radial and focus crosstalk scheme can be described by the following equation (I): Where IFESRVO represents the improved focus error signal and y1j and y2j are vector components for scaling. Instead, scalar adaptive scaling factors γ1 and γ2 may be applied which can be updated by minimising a cost function J(y1, y2), which is able to imply the radial to focus crosstalk components remaining in the focus error signal.

    摘要: An optical beam shaper comprises a polarization-dependent phase adjustment member which applies a phase pattern of equal magnitude and opposite sign to two orthogonal polarization states. In a preferred embodiment the beamer shaper is a dif tractive element made of a birefringent material, such as a photo-polymerizable liquid crystal polymer frozen in a uniaxial alignment, said dif tractive element comprising a plurality of zones, each zone having a stepped thickness defining a plurality of steps. The beam shaper can be used to introduce astigmatism to a polarized light beam or to undo the astigmatism to a beam with an orthogonal polarization state. The beam shaper is advantageously used within a detection device, such as a fluorescence scanner.

    摘要: The invention relates to a holographic data storage medium (4) in which there are sections (20) which are used for data storage and sections (21) which are not. A diffractive structure (30a, 30b) is provided in respect of one or more of the unused sections (21), possibly at each of the boundaries between the used (20) and unused sections (21) or within the volume of a respective unused section (21) of the data storage volume. During read-out, a reference wave (6) is diffracted by the diffractive structure (30b) such that it enters a used section (20) (from the right) in a direction substantially perpendicular to the optical axis (16) of the signal wave (26). During recording, a reference wave (2) is diffracted by the diffractive structure (30a) such that it enters the used section (20) (from the left) in a direction substantially perpendicular to the optical axes (1b) of the signal wave (1).
