Abstract
The invention relates to an OCT system comprising an OCT light source, an OCT evaluation unit, a first OCT light guide, a second OCT light guide and a changeover module. The light from the OCT light source passes through the changeover module. In a first state of the changeover module, the OCT light is passed to an entry end of the first OCT light guide. In a second state of the changeover module, the OCT light is passed to an entry end of the second OCT light guide. A scanning device assigned to the first OCT light guide is arranged between the changeover module and the object plane. The OCT system according to the invention can be used in a flexible manner.
Claims12
An OCT system comprising:
- a surgical microscope (21) having an observation beam path (23) and an object plane (24);
- an OCT light source (15) generating OCT light;
- a changeover module (18) operatively coupled to receive said OCT light from said OCT light source;
- a first OCT light guide (19) having an entry end operatively coupled to said changeover module and defining a first OCT beam path coupled into said observation beam path (23);
- a scanning device (29) assigned to the first OCT light guide (19);
- a second OCT light guide (20) having an entry end operatively coupled to said changeover module and defining a second OCT beam path coupled into a beam path of an optical device, a surgical instrument (22), or an OCT handpiece;
- and
- an OCT evaluation unit,
- wherein OCT light from the OCT light source (15) passes through the changeover module (18), said OCT light is passed to the entry end of the first OCT light guide (19) in a first state of the changeover module (18), said OCT light is passed to the entry end of the second OCT light guide (20) in a second state of the changeover module (18), and wherein said scanning device (29) is arranged between the changeover module (18) and said object plane.
A method for carrying out an OCT measurement comprising the steps of:
- generating OCT light from an OCT light source (15);
- passing said OCT light to an object via a changeover module (18), a first OCT light guide (19), a scanning device (29), and an observation beam path (23) of a surgical microscope (21);
- and
- evaluating the light reflected by the object in an OCT evaluation unit (16);
- or
- actuating the changeover module (18) to pass said OCT light from the OCT light source (15) to an object via a second OCT light guide (20) and a beam path of an optical device, a surgical instrument (22), or an OCT handpiece;
- and
- evaluating the light reflected by the object in the OCT evaluation unit (16).
