    摘要: A projection-type color image display system uses a reflective liquid crystal (LC) light modulator (24) and a polarizing beam-splitter (22) for separating the incoming and reflected light. Light from the source arrives on a first axis (28) and is reflected outward, with the imposed image, along a second axis (30) through a projection lens (26). In order to produce a high contrast image, a pre-polarizer (36, 42, 48) and/or post-polarizer (44, 50) are used to restore the selectivity and, consequently, optical system contrast for the wide “cone of acceptance” of light rays which are common in projection systems. In order to improve the system contrast, the pre- and/or post-polarizer is arranged along the first and second axis, respectively, with its polarizer absorbing axis extending parallel to the normal n of the reflective surface (34, 46) of the PBS.

    摘要: An optical head scans the information layer (3) of an optical record carrier (1) by means of a radiation beam (13). Optical aberrations in the beam such as coma and spherical aberration, caused by tilt and thickness variations in the optical disc respectively, are compensated by an aberration compensator (27) arranged in the radiation beam. The tilt or thickness variation is measured by a detector (30) and used to control the aberration compensator. The radiation beam is focused onto the information layer by an objective system (11). A displacement of the objective system in the transverse direction (26) as used for radial tracking of the optical beam, causes a mismatch between the wavefront to be compensated and the wavefront introduced by the aberration compensator (27). The detrimental effects of the mismatch are reduced by compensating only part of the aberration. The degree of compensation depends on the maximum displacement of the objective system and the tolerable wavefront error.

    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.
