A Vehicle Acceleration and Attitude Sensor is provided, having use as a vehicle collision sensor for activation of air bags and the like, and as well for detecting within off road vehicles an unsafe attitude of the vehicle. A compressible carrier medium of light or other wave energy, such as translucent foam, is coupled with a light or other wave energy source and a receiver. An inertial mass, which may consist of the carrier medium itself, is in contact with the carrier medium and operates to compress the carrier medium when the apparatus is either accelerated or tilted beyond a predetermined amount. A signal coupler and processor are associated with the energy source and receiver. The apparatus operates on the principle whereby compression of a scattering medium or an integrating cavity, within the region surrounding a light or other wave energy source, will increase the intensity of the wave energy. This increased intensity is translated into a measurement of the acceleration or tilt experienced by the sensor.
