Abstract
Accelerometer with an inertial mass suspended in a housing, and with apparatus for deriving a signal for the measurement of a force acting on the inertial mass. The accelerometer measurement is thereby made by means of a light source located inside the inertial mass, the light from which is transmitted through hiles in the inertial mass. The light transmitted through the holes strikes photo elements positioned on the housing. This apparatus makes possible a direct evaluation of the signals, whereby, if necessary, digital words can be produced for the determination of the position of the inertial mass within the housing. In one embodiment the inertial mass has two holes therein which transmit light to two groups of photo elements.
