An optical imaging device includes at least a first and a second image recording units for generating a first and a second original images of an object, wherein the original images differ at least with regard to an image parameter, wherein the image recording units are arranged such that original images are recorded from the same perspective, an image processing unit configured to further process the original images and an image display unit configured to reproduce displayed images generated from the processed original images. The image processing unit is configured to supplement at least one of the two original images with image information from the other original image to generate a displayed image. In addition, a corresponding method is provided.

Optical imaging device and method for improving displayed images

A method for correcting a shading in a digital image of a three-dimensional observation object obtained by at least one image sensor of an optical observation device is provided. The three-dimensional observation object is illuminated by illumination light and an intensity distribution, and an inhomogeneity in an image brightness is present in the digital image of the three-dimensional observation object. The method includes ascertaining a topography of the three-dimensional observation object, correcting the inhomogeneity in the image brightness of the digital image based on the topography of the three-dimensional observation object and the intensity distribution of the illumination light. In addition, an optical observation system is provided to perform the method.

Method for carrying out a shading correction and optical observation device system

A stereoscopic imaging device includes at least a first and a second image recording unit configured to record a first and a second original image of an object from different perspectives, wherein the original images differ at least with regard to one item of image information, an image display unit for imaging displayed images, an image processing unit for further processing the original images, and the image processing unit is configured to supplement at least one of the two original images with at least one item of image information from the other original image to generate a displayed image. In addition, a method for generating at least one displayed image that can be imaged on an image display unit is provided.

Stereoscopic imaging device and method for image processing

A microscope includes an illumination unit for illuminating a region of a specimen to generate an illuminated region, an imaging optical unit for magnified imaging of the illuminated region, an image sensor disposed downstream of the imaging optical unit for capturing the magnified image of the illuminated region, a camera for recording an overview region of the specimen without using the imaging optical unit and a control unit for controlling the image sensor and the camera. The overview region includes a part of the illuminated region and a non-illuminated region of the specimen. The control unit actuates the camera to make a recording of the overview region. The control unit actuates the image sensor to cause a recordation of the magnified image of the illuminated region. The control unit generates an overview image based on the recording of the overview region and the recording of the magnified image.

Microscope having an imaging optical unit for recording

A microscopy method for quantifying a fluorescence of protoporphyrin IX includes: imaging an object region onto a first detector field and a second detector field, wherein a first optical filter and a second optical filter, respectively, are arranged in the beam paths between the object region and the detector fields, the first optical filter and second optical filter respectively having a wavelength-dependent transmission characteristic; exciting at least a first fluorescence of protoporphyrin IX and a second fluorescence; recording first images and second images; and determining a spatially dependent fluorescence intensity of the first fluorescence in the object region by virtue of determining values representing a fluorescence intensity at locations in the object region, wherein the values are determined on the basis of the radiation intensities of the two detector fields detected in a spatially dependent manner and the spatially dependent wavelength-dependent detection efficiencies of the two detector fields.

Microscopy system and microscopy method for quantifying a fluorescence

A microscopy method includes illuminating an object with illumination light, recording a first color image of the illuminated object by a color image sensor suitable for recording colors of a first gamut, producing a second color image of the object, the second color image including pixels that each have assigned a color from a second gamut, depicting the second color image by a display apparatus suitable for rendering colors of the second gamut, wherein the producing the second color image includes determining the colors at the pixels of the second color image by applying a color transfer function to the colors of the corresponding pixels of the first color image, the color transfer function mapping input colors onto output colors, and the color transfer function mapping those input colors that belong to the first gamut but not to the second gamut onto output colors that belong to the second gamut.

Microscopy method

A control apparatus for a phacoemulsification system is disclosed. The control apparatus is configured to supply electrical energy to an actuator for a phaco needle during a plurality of time intervals, wherein the time intervals includes a first time interval, in which electrical energy for pulses with a constant maximum amplitude is supplied, a second time interval following the first time interval, wherein electrical energy with a value equal to zero is supplied, and a third time interval following the second time interval, wherein the third time interval has a first time duration in which electrical energy for pulses which have a lower constant amplitude than the maximum amplitude during the first time interval is supplied.
