Abstract
A device for recording images is provided, an image-recording device and an illumination device being arranged on the same side of a specimen plane in said device. The image-recording device has illumination portions, for example individual light sources, which are actuatable independently of one another in order to be able to illuminate a specimen in the specimen plane at different angles and/or from different directions. In this way, it is possible to record a plurality of images with different illuminations, which can be combined to form a results image with improved properties.
Claims12
A device for recording images, comprising:
- an image-recording device;
- an illumination device arranged around an optical axis of the image-recording device;
- a further image-recording device;
- and
- at least one of a further illumination device that couples light into a beam path of the image-recording device, or an additional illumination device that couples the light into a beam path of the further image-recording device,
- wherein the illumination device has a cut-out to facilitate a passage of light to the image-recording device,
- wherein the illumination device has a plurality of independently actuatable illumination portions,
- wherein the image-recording device and the illumination device are arranged on a same side of a specimen plane of the image-recording device,
- wherein, with respect to the image-recording device, the further image-recording device is on an opposite side of the specimen plane,
- wherein an angle between adjacent illumination portions of the illumination device as seen from the specimen plane is less than or equal to an angle defined by a numerical aperture of the image-recording device, and
- wherein the further image-recording device differs from the image-recording device with respect to at least one of numerical aperture, working distance, magnification or resolution.
A method for recording a plurality of images using a device comprising:
- an image-recording device;
- an illumination device arranged around an optical axis of the image-recording device;
- a further image-recording device;
- and
- at least one of a further illumination device that couples light into a beam path of the image-recording device, or an additional illumination device that couples the light into a beam path of the further image-recording device,
- wherein the illumination device has a cut-out to facilitate a passage of light to the image-recording device,
- wherein the illumination device has a plurality of independently actuatable illumination portions,
- wherein the image-recording device and the illumination are arranged on a same side of a specimen plane of the image-recording device;
- wherein, with respect to the image-recording device, the further image-recording device is on an opposite side of the specimen plane,
- wherein an angle between adjacent illumination portions of the illumination device as seen from the specimen plane is less than or equal to an angle defined by a numerical aperture of the image-recording device, and
- wherein different illumination portions of the illumination device of the device are activated for various images of the plurality of images,
- the method comprising:
- combining the plurality of images to form a result image with improved image properties.
