Abstract
The invention relates to a sensing system comprising at least one light emitting source, a sensing element comprising a sensing area, and an optical means for directing light being emitted by the at least one light emitting source onto the sensing area of the sensing element and for directing light being transmitted or reflected from the sensing area of the sensing element to an integrated interrogator; the interrogator having at least one detector configured for detecting part of the spectrum of the light directed from the sensing area of the sensing element.
Claims11
A sensing system comprising:
- at least one light emitting source;
- a sensing element comprising a sensing area;
- and
- an optical director configured to direct light emitted by the at least one light emitting source onto the sensing area of the sensing element, and to direct light transmitted or reflected from the sensing area of the sensing element to an integrated interrogator;
- wherein the integrated interrogator comprises at least two detectors, wherein each detector comprises a filter and is configured to detect part of the spectrum of the light directed from the sensing area of the sensing element, and wherein each filter is positioned on a top face of its respective detector or within its respective detector, as viewed from a direction of the light leaving the sensing element.
