    摘要: A optical scanning device (1) for scanning an information layer (2) with a radiation beam (25) in a writing mode and a reading mode comprises a radiation source (7) for emitting the beam and an objective lens (10) for converging the beam so as to form a scanning spot (19) in the information layer. The device also includes a scanning spot power switch (20) for switching the size of the cross-section of the beam between a first size at the writing mode and a second, larger size at the reading mode so as to switch the rim intensity of the beam between a first intensity level (Irim,writing) at the writing mode and a second, higher intensity level (Irim,reading) at the reading mode, thereby switching the light power of the scanning spot between a first power level (Pwriting) at the writing mode and a second, lower power level (Preading) at the reading mode.

    摘要: A method is proposed that allows a static design of an optical pickup unit (OPU) that delivers two output beams (30, 32). Both laser beams (30, 32) result in successive spots, which have the appropriate characteristics. In this OPU concept both read and write spots are present at the same time, and they are sufficiently spaced apart in the focus direction. This allows switching from the read situation to the write situation by introducing an appropriate focus offset in the electronics. The two output beams (30,32) are generated from a polarized incoming beam, said polarized incoming beam is split by a tilted birefringent grating (18).

    摘要: The present invention provides a discretely adjustable lens (300) that is controllable by means of electrostatic or electrowetting forces. The lens provides two accurately reproducible and freely designable lens states that are defined by interfaces between one out of two fluids (120,121) and at least one lens face (155). Changing place of the fluids by means of electrostatic or electrowetting forces provides for switching between the lens states. The lens may, for example, provide a macro lens option in a camera lens arrangement.

    摘要: A variable lens (100; 200; 300; 400; 500; 600) is described. The lens (100; 200; 300; 400; 500; 600) comprises a chamber (125) defined by at least one side wall and having an optical axis (90) extending longitudinally through the chamber. The chamber (125) contains a first fluid (130) and a second fluid (140) in contact over a meniscus (150) extending transverse the optical axis (90). The perimeter of the meniscus (150) is constrained by the side walls (125). The fluids (130, 140) are substantially immiscible, and have different indices of refraction. At least one pump (110; 112, 114, 116, 152; 422) is arranged to controllably alter the position of the meniscus (150) along the optical axis (90) by altering the relative volume of each of the fluids (130, 140) contained within the chamber (125).
