  • EXTRINSIC FABRY-PEROT INTERFEROMETER METALLIC SURFACE SENSOR
    Publication number: 20260202185
    Abstract: The present invention relates to a method of adapting an Extrinsic Fabry-Perot interferometer (EFPI) to measure the distance between a reflective surface of the EFPI and a metal surface. In one embodiment of the invention, the EFPI is embedded into a mold wall and measures the shrinkage gap size formed between a mold wall and a metal surface as the molten metal solidifies. In another embodiment a plurality of EFPI is placed in any array. The EFPI array and a cast metal surface are configured to move relative to each other such that the distance between the cast metal surface and the reflective surface of the EFPI is measured at a plurality of locations. The present invention further relates to an array of a plurality of EFPI.
