Abstract
It is proposed to use self-mixing interferometry for determining an absorption. The monitoring device for use in lateral flow testing for detecting presence or amount of an analyte in a liquid includes a housing, the housing including a carrier holder for holding a carrier for transport of the liquid; at least a first light source which is a resonant-cavity light source having a cavity; and an evaluation unit, operationally connected to at least the first light source for detecting a measurement signal. The first light source is structured and arranged to illuminate with light a test range in a test area of a carrier held in the carrier holder; and to couple back into the cavity of the first light source a portion of the light coming back from the test range.
