An ultrasound transducer of a vehicle system includes a support member that attaches to and connects to the bottom portion of a membrane of the ultrasound transducer and supports the membrane, wherein the support member includes one or more cantilevers with a first end attaching to the membrane and a second end attaching to a support portion of the support member that attaches to the substrate, wherein the cantilever extends across and floats above the substrate, wherein the first end of the cantilever includes a stub extending away from a surface of the cantilever, wherein the stub extends away from the surface without contacting the substrate, wherein the one or more cantilevers includes one or more piezoelectric layers on the surface of the cantilever.

A spectrometer device includes an optical interference filter which is designed to filter specific wavelength ranges of an incident light beam on passage through the optical interference filter. The spectrometer device also includes a detector device which is designed to detect the filtered light beam. Further, the spectrometer device includes a focusing device with a reflective surface. The focusing device is designed to focus the filtered light beam onto the detector device by reflection on the surface.

Spectrometer device and method for producing a spectrometer device

The disclosure relates to an interferometer element for use in a spectrometer which includes a micromechanical Fabry-Perot filter element, which has at least a first mirror element, a second mirror element, and a third mirror element. Each of the first mirror element, the second mirror element, and the third mirror element are arranged in series in an optical path of the interferometer element, and at least one of a first distance between the first and second mirror elements, and a second distance between the second and third mirror elements is modifiable.

Interferometer element, spectrometer and method for operating an interferometer

A micromechanical mirror device, a mirror system, and a method for producing a micromechanical mirror device are disclosed. The mirror device comprises a first mirror element, which is flat, and a second mirror element, which is flat. The first and second mirror elements are arranged substantially plane-parallel. An intermediate space between the first and second mirror elements has a lower index of refraction than one or both of the first mirror element and second mirror element. The first and second mirror elements are locally spaced apart from each other by at least one support structure. The support structure overlaps with the first and second mirror elements in an axial direction, which is perpendicular to the first and second mirror elements. The support structure includes a material that is different from a material from which one or both of the first and second mirror elements are formed.

A spectrometer device includes a Fabry-Perot interferometer unit, which comprises a first carrier substrate, wherein the first carrier substrate is arranged on a lower side of the Fabry-Perot interferometer unit and includes an optical aperture. The spectrometer includes at least one of a first substrate, which is arranged on an upper side of the Fabry-Perot interferometer unit, which faces away from the lower side, and a second substrate with the first carrier substrate arranged with the lower side on the second substrate. The spectrometer further includes a photodetector device arranged on or in the at least one of the second substrate and the first substrate. A first electrical connection region of the photodetector device and a second electrical connection region of the Fabry-Perot interferometer unit are electrically contacted from the same direction.

An interferometer includes a holding element having an actuation recess, a first mirror element arranged on the holding element opposite the actuation recess, and a second mirror element arranged opposite the first mirror element at a mirror distance, to form an optical slit. The first mirror element is arranged between the second mirror element and the holding element and the optical slit is spatially separated from the actuation recess by the first mirror element. The interferometer further includes an electrode pair including a first actuation electrode in one of the mirror elements and a second actuation electrode on a side of the actuation recess opposite the first actuation electrode. The mirror distance can be varied by applying an electrical voltage to the electrode pair.

Interferometer and method for producing an interferometer

An interferometer device includes an interferometer unit with at least two mirrors disposed in parallel, wherein at least one of the mirrors is actuatable parallel to the other mirror and a first distance between the two mirrors is alterable. The interferometer device further includes at least one deflection mirror disposed downstream of the interferometer unit in a light transmission direction of light from the interferometer unit and a detector device, onto which the light is able to be aligned by the deflection mirror. The detector device includes at least two differently sensitive detection regions for transmitted wavelengths or wavelength ranges of the light, which detection regions are spatially separated from one another and able to be irradiated separately by the deflection mirror.
