An impedance matching device for matching a characteristic acoustic impedance includes an impedance matching body including a first side and an opposite second side. The impedance matching device is configured to match a characteristic acoustic impedance of a medium contacted on the first side to a characteristic acoustic impedance of a sound transducer contacted on the second side. The impedance matching body includes microstructures which have a structural extent of at most 500 nanometers along at least one spatial direction.

Impedance matching device, transducer device and method of manufacturing an impedance matching device

A device described here includes a housing and a multi-aperture imaging device. The multi-aperture imaging device includes an array of optical channels arranged next to one another and a beam-deflector for deflecting an optical path of the optical channels. In a first operating state of the device, the housing encloses a housing volume. In the first operating state of the device, the beam-deflector includes a first position within the housing volume. In a second operating state of the device, the beam-deflector includes a second position where the beam-deflector is arranged at least partly outside the housing volume.
