The beamshaping optical stack (108) is to be optically coupled to a light emitting surface of a light emitter. The beamshaping optical stack (108) comprises a first light transmitting layer (120) and a second light transmitting layer (118). The second light transmitting layer (118) comprises a first side (110) which is optically coupled to the first light transmitting layer (120) to receive light from the first light transmitting layer (120). The second light transmitting layer (118) further comprises a second side (106) which is substantially opposite the first side (110) to emit the received light into another optical medium. The second light transmitting layer (118) further comprises a geometrical structure (116) at the second side (106) to obtain a decreasing light emission with increasing light emission angles (9a) with respect to a normal (112) to the first side (110). The first light transmitting layer (120) is of a first material having a first refractive index. The second light transmitting layer (118) is of a second material having a second refractive index. The first refractive index is lower than the second refractive index.

    Abstract: In an optical storage interface apparatus, a spot-forming lens projects a light spot on an optical information carrier in response to a light beam from a light source. There is an air gap (AG) between the spot-forming lens and the optical information carrier. A gap detector (PHD2) provides a gap indication signal (GIS) that varies with the air gap (AG) in accordance with a gap indication transfer function (F). A lens-positioning arrangement (CTRL, ACT) positions the spot-forming lens with respect to the optical information carrier on the basis of the gap indication signal (GIS). The lens-positioning arrangement (CTRL, ACT) comprises a compensator (CMP) for compensating nonlinearity in the gap indication transfer function (F). A suitable compensation transfer function (G) can be established on the basis of servo control loop measurements. Accordingly, compensation can be provided without any prior knowledge of the gap indication transfer function (F).

    Abstract: The present invention relates to a domain expansion storage medium and manufacturing method with improved readout performance. The substrate of the storage medium and/or its storage layer is processed to define a predetermined shape of magnetic domains, adapted to the front of the thermal reading profile. In particular, reversed crescent shaped domains flipped in the track directions are defined. This allows improved resolution and jitter values.

    Abstract: The invention relates to an illumination system (10) comprising a light emitting device (20) and a beam shaping element (30) for generating an angular distribution (φ) of the light emitted from the illumination system. The beam shaping element is configured for recycling at least a part of the light emitted from a light emitting surface (26) of the light emitting device via reflection back towards the light emitting surface. The illumination system further comprises a diffuser (40, 42) arranged substantially parallel to the light emitting surface for diffusing at least part of the recycled light. The diffuser is constituted of a translucent diffuser (40) and/or a diffusely reflective electrode layer (42) of the light emitting device. Limiting the angular distribution by recycling light, using the beam shaping element for recycling light via reflection, reduces glare when the illumination system is used in general lighting applications. The diffuser avoids that the recycled light is confined between the beam shaping element and the light emitting surface of the light emitting element. The recycling is preferably done via total internal reflection at the beam shaping element. The presence of the diffuser improves the efficiency of the illumination system.

    Abstract: An optical scanning device (3) for scanning a record carrier (2) comprises an objective unit (20) and a diffraction element (14). The objective unit (20) is adapted to transmit an auxiliary radiation beam (21) towards the record carrier (2) in a defocused mode in addition to a main radiation beam (6) that is used for read-out and/or writing operations. The diffraction element (14) defines a measuring region (16) with respect to a spot (44) of the main radiation beam (6) so as to avoid an influence of the auxiliary radiation beam (21) on the main radiation beam (6) reflected. Hence, the performance of read-out and/or writing operations is increased.

    Abstract: A device reads and/or records marks in a track on a record carrier via near field optical recording. The device has a head including a lens to be positioned at a near field distance from a surface of the record carrier. An air gap controller is for controlling an air gap between the lens and the surface, and has an approach mode for bringing the lens from a remote distance in the far field (72) to the near field distance. Thereto the controller provides an increasing periodical excitation signal (73) for generating a sequence of approach instants (77) at which the lens approaches the surface. At the approach instants the lens has substantially zero velocity (76). The sequence of approach instants brings the lens subsequently closer to the surface. When the lens enters in the near field range (71) at one of the approach instants (77), the air gap controller is switched to closed loop mode.

    Abstract: An optical input device for measuring the movement of an object (15), e.g. a finger, is accommodated in a housing provided with a transparent window (12) for transmitting a measurement beam (13) from a diode laser (3) to the object (15) and radiation reflected by the object (15) to a detector, wherein changes in the operation of the laser cavity caused a laser diode self-mixing effect indicate the extent and direction of movement of the object. The angle of incidence (α) and/or the refractive index of the transparent window (12) nlens are selected so that at least a significant proportion of the measuring beam (13) is substantially totally internally reflected by the transparent window (12) when the object (15) is not in contact therewith. A device is also described in which at least a portion of the measuring beam (13) is directed toward a second transparent window (36) to provide a laser pointing function or enable the projection of messages or images.
