  • Patent number: 11327438
    Abstract: Techniques disclosed herein relate to modifying refractive index modulation in a holographic optical element, such as a holographic grating. According to certain embodiments, a holographic optical element or apodized grating includes a polymer layer comprising a first region characterized by a first refractive index and a second region characterized by a second refractive index. The holographic optical element or apodized grating includes a plurality of nanoparticles dispersed in the polymer layer. The nanoparticles have a higher concentration in either the first region or the second region. In some embodiments, the nanoparticles may be configured to increase the refractive index modulation. In some embodiments, the nanoparticles may be configured to apodize the grating by decreasing the refractive index modulation proximate to sides of the grating. The refractive index may be modulated by applying a monomer reservoir buffer layer to the polymer layer, either before or after hologram fabrication.

  • Patent number: 11320665
    Abstract: A device for manipulating the polarization of light which includes a first retarder-stack (Stack 1) that converts the polarization of input light from a first polarization basis vector (PBV1) to a second polarization basis vector (PBV2), a second retarder-stack (Stack 2) that returns the polarization of light from PBV2 to PBV1, and one or more optically functional layers between Stack 1 and Stack 2. Stack 1 has a plurality of layers, wherein the number of layers, retardation values, and orientations of layers in Stack 1 are selected to produce a PBV2 that is substantially spectrally-uniform over a prescribed range of wavelengths. PBV1 is a non-trivial eigen-polarization of combined Stack 1 and Stack 2. Stack 2 has a plurality of layers and Stack 2 is arranged in series with Stack 1. Alternatively, instead of two different stacks, a reflector may be used to produce a return pass through Stack 1.

  • Patent number: 11307397
    Abstract: A method for the high-resolution scanning microscopy of a specimen where the specimen is illuminated with illuminating radiation such that the illuminating radiation is focused to a diffraction-limited illuminating spot at a point in or on the specimen. The point is projected in a diffraction-limited manner in a diffraction image onto a flat panel detector having pixels. The flat panel detector, owing to the pixels thereof, have a spatial resolution which resolves a diffraction structure of the diffraction image. The point is shifted relative to the specimen into different scanning positions by an increment which is smaller than the diameter of the illuminating spot and a 3D image is generated. The pixels of the flat panel detector are divided into groups. A pre-calculated raw image is calculated for each group and are unfolded three-dimensionally to generate the image of the specimen.

  • Patent number: 11308688
    Abstract: A localization microscope including an imaging device emitting sample light from a focal plane into an image plane, including an optical-manipulation device for depth-dependent influencing of a point-spread function of the imaging and influencing the point-spread function of the imaging such that a point emitter is imaged in the image plane into an image that is rotationally asymmetrically distorted. A form of the distortion depends on the location of the point emitter with respect to the focal plane and a wavelength of the sample light. The optical manipulation device includes first and second anisotropy elements that anisotropically influence the point spread function to produce rotational asymmetry of the point emitter image. The elements are arranged one behind the other in the imaging direction, with anisotropy axes at an angle to one another. Both elements have differing neutral wavelength at which they do not anisotropically influence the point spread.

  • Patent number: 11300767
    Abstract: A method for high-resolution scanning microscopy of a sample, wherein the sample is illuminated with illumination light such that the illumination light is focused at a point in or on the sample into an illumination spot. The point is imaged into a diffraction image onto an area detector having detector elements. The area detector has a spatial resolution that resolves a diffraction structure of the diffraction image. The sample is here scanned line-wise in a grid made of rows and columns by displacing the point relative to the sample into different scanning positions with an increment width that is smaller than the diameter of the illumination spot. The area detector is read, and an image of the sample is generated from the data of the area detector and from the scanning positions assigned to said data, said image having a resolution that is increased beyond a resolution limit for imaging.
