Abstract
An accelerometer includes a mass, a spring diaphragm, a collimating lens, and an optical interferometer formed between the mass and collimating lens. The mass and spring diaphragm are preferably formed from stainless steel, but the spring diaphragm may be formed from silicon and the mass from amorphous quartz. The interferometer exists between a mirrored surface of the mass, and a partially reflective surface of the collimating lens.
