Abstract:
1. A device for optically measuring a sample, comprising: a waveguide, which supports at least an input propagation mode of light and comprises means for guiding an input beam in the input propagation mode; a probe head coupled to the waveguide to receive the input beam and comprising means for reflecting a first portion of the input beam back to the waveguide in the input propagation mode, means for directing a second portion of the input beam in the input propagation mode to a sample, means for collecting reflection of the second portion from the sample, and means for exporting to the waveguide the reflection as a reflected second portion in the input propagation mode; and a detection module comprising means for receiving the reflected first portion and the reflected second portion in the input propagation mode from the waveguide and means for extracting information of the sample carried by the reflected second portion.
