发明名称 MEASUREMENT OF OPTICAL PROPERTIES
摘要 The invention relates to an ophthalmological examination and/or treatment station that comprises, in the form of modules, a lighting device, an observation device, an optical measuring system, an evaluation unit and a patient module which is positioned immediately in front of the patient's eye. The patient module can be optically linked with the locally remote lighting device and the likewise remote measuring system in a detachable manner. The measuring system forming part of the ophthalmological examination and/or treatment station comprises an optical system with a short-coherent radiation source (9) of the Michelson interferometer-type. An optically transparent and/or diffusive, reflecting object (1) can be introduced into the measuring arm (7) of said optical system and the reference arm (5) thereof has a wavelength variation unit (39) for modifying the runtime and at last two reflectors (31a, 31b) which produce a runtime difference. The measuring system is used to measure optical properties of at least two spaced-apart areas (2a, 2b) of the transparent and/or diffusive object (1) at a measuring time in the subsecond range. The inventive measuring system allows in vivo measurements of distances, thicknesses, surface characteristics etc. which comprise measurements at different locations of an object, in an optimum manner, i.e., with reduced measurement errors.
