ABSTRACT:
An optical pressure sensor (10) uses a holographic link (41) to couple light (17) from an optical interferometer (40) to a pressure sensing element (13), and to couple return light (18) back to an optical interferometer (40). The optical link (41) uses holographic reflectors (24, 26, 27, 28, 29, and 31) to guide the light (17, 18) through the optical link (41).
