Abstract
Official abstract text for this publication.
The invention relates to a system for optical coherence tomography having an interferometer ( 20 ) which has a beam splitter ( 24 ), a reflector ( 25 ), an illumination arm ( 21 ), a specimen arm ( 22 ) and a reference arm ( 23 ). In order to increase the compactness of the system with at the same time a high image quality a specimen objective is provided in the specimen arm ( 22 ) of the interferometer ( 20 ) by means of which light is focussed into a focus lying in or on the specimen ( 1 ). Moreover, in the reference arm ( 23 ) of the interferometer ( 20 ) a reference objective is provided by means of which light is focussed onto the reflector ( 25 ). The optical properties of the specimen objective differ from the optical properties of the reference objective.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for optical coherence tomography comprising: an interferometer which has a beam splitter, a reflector, an illumination arm, a specimen arm, an outlet arm and a reference arm, light being injected into the interferometer by the illumination arm and split by the beam splitter into a partial beam extending through the reference arm towards the reflector and a partial beam extending through the specimen arm towards the specimen, the partial beams…
