    摘要: An optical scanning device can scan two different types of optical record carrier (1; 25), requiring a scanning beam (15) having different numerical apertures. The device has two stops (33; 32) at different positions along the optical axis of the path followed by the radiation beam for both types of discs. The first stop (33) limits the numerical aperture of the radiation beam when scanning the first type of record carrier (1). The second stop (32) limits the numerical aperture when scanning the second type of record carrier (25).

    摘要: A scanning device for an optical record carrier (1) comprises a high-numerical aperture dual lens objective system (10, 11) for focussing a radiation beam (7) on an information layer (3) of the record carrier. The lens (11) of the objective system closest to the record carrier is tilted by a tilt servo system in response to tilt of the record carrier. The tilt angle of the lens is preferably less than the tilt angle of the record carrier in order to reduce optical aberrations of the radiation beam such as coma and astigmatism.

    摘要: A controllable electrowetting lens system has a feedback control loop for controlling the electrode arrangement drive signals to implement an autofocus function. The feedback control loop comprising an image analysis focus detection system and a variable gain element. The gain is adjusted based on the lens condition, for example as sensed by a capacitance sensing arrangement. The autofocus control loop can be optimized to the lens characteristics (because the lens characteristics change over time) and/or to external conditions such as temperature.

The method comprises the steps of providing an electronic device comprising an optical device (10) comprising at least a first liquid (A) and being placed in front of a sensor (120), the optical device (10) having a transmittance of the part of the electromagnetic spectral range depending on an orientation of at least the first liquid (A); measuring a first intensity of the electromagnetic (EM) spectral range; changing the orientation of at least the first liquid (A); measuring a second intensity of the electromagnetic spectral range; and calculating an intensity of the part of the electromagnetic spectral range from the difference between the first intensity and the second intensity. Consequently, an intensity for a part of the EM spectral range can be measured without the need for a sensor dedicated to this part of the EM spectral range. In particular, an optical element based on the electrowetting principle is used in a mobile phone to measure the intensity of UV radiation.

    摘要: An optical device for assessing optical depth in a sample illuminated by polarized radiation from a source include two radiation guides having their end portions arranged for capturing reflected radiation from the sample. A detector measures two polarizations of the reflected radiation, and two intensities of the reflected radiation in the two radiation guides, respectively. A processor is configured to calculate two pectral functions, which are indicative of single scattering events in the sample. The processor is further configured to calculate a measure of the correlation between the two spectral functions so as to assess whether the single scattering events originate from substantially the same optical depth within the sample. Thus, the causal relation between the two spectral functions can be used for assessing whether the single scattering events giving rise to the two spectral functions come from substantially the same optical depth within the sample.
