Operating microscope having at least two camera devices
In order to achieve the aim of the invention, which is to provide an operating microscope which allows images of tissue structures to be captured and displayed as accurately as possible, an operating microscope comprising a first camera device (1) for capturing and displaying a reflection image of an object is characterised by a second camera device (2) for simultaneously capturing and displaying a further image of the object.
1 . An operating microscope, comprising:
a first camera device having at least two cameras for capturing a three-dimensional impression and representing the three-dimensional impression as at least one reflection image of an object,
an image processing device configured to composite from the at least one reflection image and the at least one further image an overall image;
wherein the at least one reflection image and the at least one further image are selected by the image processing device according to a selection criterion defining a predefined image sharpness quality; and
a second camera device having at least two cameras for simultaneously capturing another three-dimensional impression and representing the another three-dimensional impression as at least one further image of the object.
2 . The operating microscope as claimed in claim 1 , wherein at least one of the first and second camera devices performs image recordings in the video mode.
3 . The operating microscope as claimed in claim 1 , wherein the representation of the images takes place in real time.
4 . The operating microscope as claimed in claim 1 , wherein at least one of the first and second camera devices performs three-dimensional image recordings.
5 . The operating microscope as claimed in claim 1 , wherein the first and second camera devices acquire different light intensities.
6 . The operating microscope as claimed in claim 1 , wherein the first and second camera devices operate with different exposure times.
7 . The operating microscope as claimed in claim 1 , wherein the at least one further image is a fluorescence image of the object.
8 . The operating microscope as claimed in claim 1 , further comprising at least one illumination source having a fluorescence excitation light source.
9 . The operating microscope as claimed in claim 1 , further comprising a blocking filter placed in front of the first and second camera devices so that a light pencil component incident on any of the at least two cameras passes therethrough.
10 . The operating microscope as claimed in claim 9 , wherein the blocking filter at least suppresses light with a wavelength between 480 nanometer (nm) and 490 nm.
11 . The operating microscope as claimed in claim 8 , wherein the at least one illumination light source is configured to block fluorescence at a wavelength range out from illumination spectrum.
12 . The operating microscope as claimed in claim 1 , further comprising a bandpass filter placed in front of the second camera device so that a light pencil component incident on any of the at least two cameras passes therethrough.
13 . The operating microscope as claimed in claim 1 , further comprising an OCT apparatus examining a specimen by a sampling light.
14 . The operating microscope as claimed in claim 1 , wherein image sensors which are sensitive for infrared light, preferably for infrared light from the wavelength range of 1000 to 1500 nm, are provided in the first and/or second camera device.
15 . The operating microscope as claimed in claim 1 , wherein the at least two cameras of the second camera device captures fluorescence images of the object for three-dimensional image recordings.
16 . An operating microscope, comprising:
a first camera device having at least two cameras for capturing a three-dimensional impression and representing the three-dimensional impression as at least one reflection image of an object;
a second camera device having at least two cameras for simultaneously capturing another three-dimensional impression and representing the another three-dimensional impression as at least one further image of the object; and
an image processing device configured to composite from the at least one reflection image and the at least one further image an overall image;
wherein the at least one reflection image and the at least one further image are selected by the image processing device according to a selection criterion defining a predefined image sharpness quality.
17 . The operating microscope as claimed in claim 16 , wherein at least one beam splitter is directly interposed in the path between the object and the at least two cameras.
18 . The operating microscope as claimed in claim 16 , wherein the at least two cameras are sensitive in all of the visible spectrum.
