  • Publication number: 20180176473
    Abstract: A multi-aperture imaging device includes a one-line array of adjacently arranged optical channels and beam-deflecting unit for deflecting an optical path of the optical channels. The beam-deflecting unit includes a first position and a second position between which the beam-deflecting unit is translationally moveable along a line extension direction of the one-line array. The beam-deflecting unit is configured such that it deflects the optical path of each optical channel into mutually different directions depending on whether it is located in the first position or in the second position.

  • Publication number: 20180176437
    Abstract: The fact that a beam-deflecting device can be produced cost-effectively and without any losses of optical quality of the multi-aperture imaging device is used when a carrier substrate is provided for the same, wherein the carrier substrate is common to the plurality of optical channels and is installed with a setting angle, i.e. oblique with respect to the image sensor in the multi-aperture imaging device such that a deflection angle of deflecting the optical path of each optical channel is based, on the one hand, on the setting angle and, on the other hand, on an individual inclination angle with respect to the carrier substrate of a reflecting facet of a surface of the beam-deflecting device facing the image sensor, the reflecting facet being allocated to the optical channel.

  • Patent number: 9930237
    Abstract: The invent on relates to a multichannel optics image capturing apparatus wherein at least a first channel includes anamorphic mapping optics and the first channel has an at least partial field of view overlap with a second channel. Additionally, the invention relates to a multichannel optics image capturing apparatus including at least a first channel and a second channel, wherein the first channel has an at least partial field of view overlap with the second channel, and the second channel includes a first two-dimensional arrangement of detector pixels and the second channel includes a second two-dimensional arrangement of detector pixels, and the first two-dimensional arrangement is incongruent with respect to the second two-dimensional arrangement. The suggested solution achieves that the resolution of an overall image composed of individual images of the channels is essentially distance-independent with respect to an object to be captured.

  • Patent number: 8717485
    Abstract: An improved ratio between hardware/manufacturing expenditure, on the one hand, and picture quality, on the other hand, when using a multi-channel optical element is achieved in that the samples of the pixels are arranged in accordance with an imaging direction from which the optical element images objects on the respective pixel, or with a lateral imaging position in a focal-depth area that is imaged to the respective pixel by the optical element, and when the distribution, thus arranged, of samples of the pixels is interpolated at intersection points of a regular grid extending over the entire distribution of the samples. In this manner, processing is standardized across the entire picture, so that transition problems between the subareas are avoided.

  • Patent number: 8593562
    Abstract: A refraction at a suitably structured surface for example with an arrangement of the same between image plane and mapping optics is used to realize on the one hand a desired aliasing filtering or spatial low-pass filtering on the image plane wherein on the other hand the manufacturing of such structured surfaces may be realized in a cost-effective way. In addition to that, the plate thickness except for the amplitude of the surface structure and aspects of the stability of the plate is of no importance for handling the same, so that the integration into optical systems is facilitated.
