Abstract
An ophthalmic device and an arrangement for generating images with expanded dynamic range and a corresponding method for generating images with expanded dynamic range have at least one beamsplitter, in particular with an asymmetric splitting ratio, and at least two image sensors, wherein the image sensors are reflected into a common imaging beam path by the at least one beamsplitter.
Claims15
An ophthalmic apparatus for generating an image with expanded dynamic range:
- comprising at least one beamsplitter;
- and
- at least two image sensors;
- wherein the image sensors are reflected into a common imaging beam path by the at least one beamsplitter;
- and
- wherein the apparatus is an ophthalmic device.
A method for generating images with expanded dynamic range by means of an ophthalmic device comprising at least one beamsplitter and at least two image sensors, wherein the image sensors are reflected into a common imaging beam path by the at least one beamsplitter and the following steps are carried out, comprising the steps of:
- recording individual images with different radiant energies by means of the image sensors;
- and
- generating a total image with expanded dynamic range from the individual images.
A non-transitory computer-readable medium for storing a computer program for generating images with expanded dynamic range by means of an ophthalmic device comprising at least one beamsplitter and at least two image sensors, wherein the image sensors are reflected into a common imaging beam path by the at least one beamsplitter and the following steps are carried out, the computer program performing the steps of:
- recording individual images with different radiant energies by means of the image sensors;
- and
- generating a total image with expanded dynamic range from the individual images.
