Classification: CPC A  G | IPC A  G

Claim 0:
1. A fibre endoscope system comprising
a catheter with a probe head for entering into a body cavity, duct, or vessel adjacent a sample region to be measured;
a source fiber with a first fiber ending remote from the probe head;
a signal fiber with a second fiber ending also remote from the probe head but separate from the source fiber;
a sampling fiber with a third fiber ending disposed at the probe head; and
a fiber coupler disposed inside the probe head at a distal end of the catheter and configured to optically couple at least
the source fiber to the sampling fiber, and
the sampling fiber to the signal fiber;

wherein a sampling fiber length of the sampling fiber between the fiber coupler and the third fiber ending is shorter than a source fiber length of the source fiber between the fiber coupler and the first fiber ending by at least a factor two.
