摘要： An optical scanning device 1 detects an information signal from an optical record carrier 2 using differential interference contrast. Two radiation beams 13a, 13b are generated and focused to two distinct spots 15a, 15b respectively displaced along a data track on the information layer of an optical record carrier. The relative positions of the spots in lands and pits can generate a path length difference between the reflected beams 17a, 17b. This path length difference causes the beams to interfere either constructively or destructively, depending on the relative land/pit position in the data track of the spots. This interference causes a detectable signal to be generated, the signal being representative of a transition from a pit to a land on the information layer 4 or vice versa.

摘要： An optical head (1) for scanning an optical record carrier (2) is provided with a compensator (16) for compensating the field curvature aberration of the objective system (18) caused by operation of the optical head at a different field angles. A surface of the compensator (16) comprises a phase structure in the form of annular areas (52, 53, 54, 55, 56), the areas forming a non-periodic pattern of optical paths of different lengths. The optical paths change as a function of field angle and form a field angle-dependent wavefront deviation that compensates field curvature of the optical head.

摘要： A lighting unit (1), comprising a bowl shaped reflector (6), and a plurality of point shaped light sources (2) arranged inside the reflector. The unit further comprises a mixing chamber (4) in which the point shaped light sources (2) are arranged, and a scattering layer (5) covering the mixing chamber (4). The scattering layer (5) is partially reflecting and partially transmitting, thereby ensuring that light emitted by the point shaped light sources (2) is mixed in the mixing chamber (4) before reaching the reflector. This allows light emitted from the mixing chamber via the reflector to be conceived as one beam. In use, light from the point shaped light sources may be reflected by the scattering layer and then scattered by the scattering layer so that the reflector generates a beam similar to a halogen beam.
