  • Patent number: 10509147
    Abstract: An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L1) comprising a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array (S1) of light sources (1) for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N?1. High-contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.

  • Patent number: 10444477
    Abstract: The wafer stack (100) comprises a first wafer (OW1) referred to as optics wafer and a second wafer (SW) referred to as spacer wafer, said optics wafer (OW1) having manufacturing irregularities. The spacer wafer (SW) is structured such that it at least partially compensates for said manufacturing irregularities. The corresponding method for manufacturing a device, which in particular can be an optical device, comprises carrying out a correction step for at least partially compensating for manufacturing irregularities. Such a correction step comprises providing a wafer (SW) referred to as spacer wafer, wherein that spacer wafer is structured for at least partially compensating for said manufacturing irregularities. Those manufacturing irregularities may comprise a deviation from a nominal value, e.g., a irregularities in focal length. The invention can allow to mass produce high-precision devices at a high yield.

  • Publication number: 20190271828
    Abstract: The present disclosure describes imaging techniques and devices having improved autofocus capabilities. The imaging techniques can include actively illuminating a scene and determining distances over the entire scene and so that a respective distance to each object or point in the scene can be determined. Thus, distances to all objects in a scene (within a particular range) at any given instant can be stored. A preview of the image can be displayed so as to allow a user to select a region of the scene of interest. In response to the user's selection, the imager's optical assembly can be adjusted automatically, for example, to a position that corresponds to optimal image capture of objects at the particular distance of the selected region of the scene.

  • Publication number: 20190123213
    Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.
