Abstract:
An optical system, in particular for use in the automobile sector, includes at least one compensation element for compensating at least one temperature-related dimension change in the optical system. The at least one compensation element includes a housing which is variable in length in at least one dimension, as well as a fluid expansion medium accommodated in the at least one housing. For example, the optical system may include at least one camera system, for example a video system, the at least one camera system including at least one camera base and at least one imaging system which is connected to the at least one camera base and having at least one optical axis as well as at least one imaging sensor.
Abstract:
A system includes a stored table comprising a plurality of rows and at least one column, each of the plurality of rows associated with a node of a hierarchy, and one of the at least one columns implicity representing a position of a row's associated node within the hierarchy, wherein a Structured Query Language query is received and, response to the query, one or more values of the one of the at least one columns are determined and one or more properties of the hierarchy are determined based on the one or more values.
Abstract:
An image sensor and a method for manufacturing an image sensor are described in which the image sensor includes at least one substrate having a plurality of light-sensitive elements forming a sensor field and first microfilter elements for wavelength-selective filtering of incident light. The first microfilter elements are attached to a transparent carrier made of glass or a transparent film, for example. A first microfilter element is situated in front of a portion of the light-sensitive elements for wavelength-selective filtering of light striking the light-sensitive element. No microfilter element is situated in front of a further portion of the light-sensitive elements.

Abstract:
An image acquisition system, in particular for automotive applications, includes: a substrate; an image sensor mounted on the substrate and contacted via contact points; an optically transparent sealing compound that covers the image sensor, the contact points, and a portion of the upper substrate side; an optical device being arranged or secured in or on the sealing compound. The optical device can be placed into the sealing compound after shaping of the sealing compound or directly. Furthermore, the optical device can also be arranged directly by shaping the sealing compound. Manufacture of the image acquisition system can be incorporated into a board populating process.

Abstract:
A camera system for detecting the surroundings of a vehicle through a vehicle window pane (1), having a camera (2) having an image sensor (4), a first optical radiation (6) generated by the vehicle surroundings detectable by a sensor surface (10) of the image sensor (4), and a radiation source (3) for emitting a second optical radiation (7). At least a portion of the emitted second optical radiation (7) is detectable by the sensor surface (10) of the image sensor (4), and the portion of the second optical radiation (7) detected by the sensor surface (10) is a function of a state of window pane (1). The first and second optical radiation (6, 7) are jointly detectable via at least one partial area (8, 9) of the sensor surface (10). A method is also provided for detecting the surroundings of a vehicle employing the camera system.

Abstract:
A fiber optic sensor head for detecting the shape or the distance of a test object has an optical fiber, in particular a glass fiber, for conducting and returning partial beams to and from the test object, and an injection/extraction lens on the test object side. For conducting partial beams, injected on the sensor head side and having an optical path length difference, to the test object and returning partial beams injected on the test object side without an optical path length difference, a Fizeau interferometer having a nondiscrete design is associated with the optical fiber and compensates for the optical path length difference between the partial beams.
