Abstract
Light from a light source (10) is transmitted along an optical fiber (12) through a sensor (14) to opto-electronics (16). The sensor includes a cantilevered beam (20) that flexes in response to acceleration causing its free end (26) to move. Light from the optical fiber (12) is transmitted along an optical fiber to a terminal end (30) thereof and across a gap (34). Light transmitted across the gap is returned to the optical fiber by a mirror (FIG. 2 ) or received by a free end (36) of a second optical fiber (FIG. 1) and conveyed to the opto-electronics. The beam member is configured with an appropriate stiffness that under acceleration, the beam flexes moving its free end sufficiently to change measurably through transmission of light across the gap to the opto-electronics.
