A system and method for creating a stable and reproducible an optical interface for measuring blood glucose levels in biological tissue are disclosed, including a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic can include a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal can be enhanced by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. A medium can be injected between the disposable and the skin to match the respective refractive indices and enhance the signal collection of the sensor.

L'invention concerne un système et un procédé destinés à la création d'une interface optique stable et reproductible permettant de mesurer la glycémie d'un tissu biologique, comprenant un capteur à double prisme fixé à une optique jetable comportant une lentille de focalisation et une fenêtre optique. L'optique jetable colle à la peau pour permettre au patient d'effectuer plusieurs lectures ou relevés au même emplacement. L'optique jetable peut comprendre une surface de Petzval placée contre la peau afin de maintenir le point focal du faisceau optique sur la surface de la peau. Par ailleurs, l'intégrité du signal de détection peut être augmentée par variation du taux de rotation des prismes dans le temps par rapport à la fréquence de balayage du capteur. Un fluide peut être injecté entre l'optique jetable et la peau pour harmoniser les indices de réfraction respectifs et augmenter la capacité de détection du signal du capteur.
