    摘要: A multi-spectral camera comprises a blocking element (201) having at least one hole (203) allowing light through. A dispersive element (205) spreads light from the at least one hole (203) in different wavelength dependent directions and a lens (207) focuses light from the dispersive element (205) on an image plane (209). A microlens array (211) receives light from the lens (207) and an image sensor (213) receives the light from the microlens array (211) and generates a pixel value signal which comprises incident light values for the pixels of the image sensor (213). A processor then generates a multi-spectral image from the pixel value signal. The approach may allow a single instantaneous sensor measurement to provide a multi-spectral image comprising at least one spatial dimension and one spectral dimension. The multi-spectral image may be generated by post-processing of the sensor output and no physical filtering or moving parts are necessary.

    摘要: The invention relates to an optical recording apparatus comprising means for optimizing a write strategy in a recording process. The apparatus comprising a radiation source for emitting a radiation beam in accordance with the write strategy, a read unit so as to provide a read signal, a bit detector for providing modulation bits corresponding to the read signal, a processing unit for grouping the modulation bits into modulation bit sequences and for correlating each modulation bit sequence of the read signal to a reference level, the reference level corresponding to the average amplitude of the read signal for a given modulation bit sequence. Average transition shifts of leading and/or trailing edges are determined based on the position of the reference levels, and at least one of the one or more write parameters in the write strategy is optimized in an optimization process based on the relative values of the reference levels. Optionally, the asymmetry of an optical effect may be determined from the reference levels so that the write strategy is optimized based on the asymmetry.

    摘要: A series of structured lighting patterns are projected on an object. Each successive structured lighting pattern has a first and second subset of intensity features such as edges between light and dark areas. The intensity features of the first set coincide spatially with intensity features from either the first or second subset from a preceding structured lighting pattern in the series. Image positions are detected where the intensity features of the first and second subset of the structured lighting patterns are visible in the images. Image positions where the intensity features of the first subset are visible are associated with the intensity features of the first subset, based on the associated intensity features of closest detected image positions with associated intensity features in the image obtained with a preceding structured lighting pattern in said series. Image positions where the intensity features of the second subset are visible, between pairs of the image positions associated with intensity features of the first subset, with intensity features of the second subset between the intensity features associated with the pair of positions. The associated intensity features in a final structured lighting pattern of the series are used to identify the intensity features of the final structured lighting pattern for the determination of 3D surface position information.

    摘要: The invention relates to a detection system for determining whether a light contribution of a light source is present at a selected position within a 2D scene. The light contribution includes an embedded code comprising a repeating sequence of N symbols. The detection system includes a camera and a processing unit. The camera is configured to acquire a series of images of the scene via specific open/closure patterns of the shutter. Each image includes a plurality of pixels, each pixel representing an intensity of the light output of the light source at a different physical position within the scene. The processing unit is configured to process the acquired series of images to determine whether the light contribution of the first light source is present at the selected physical position within the scene by e.g. correlating a sequence of pixels of the acquired series corresponding to the selected physical position with the first sequence of N symbols.

    摘要: The present invention relates to an optical record carrier recording apparatus and method for recording data on a phase-change optical record carrier (55) storing a state information about the location of crystalline and non-crystalline areas of the record carrier (55). In order to provide the possibility to write with different writing speeds on the record carrier, writing means (54) for recording data on the record carrier (55) can be switched between different writing modes. The first writing mode is used if the recording apparatus (5) is in a high power mode, e.g. supplied with power from a mains power supply and if a crystalline (unwritten) area is available on the record carrier (55). If no crystalline area is available or if the recording apparatus (5) is in a low power mode, the second writing mode having a lower writing speed is preferably used.
