Accelerometers for space applications are typically based on a capacitive readout. Here we present the design of an accelerometer based on a classical mass spring mechanical system with an interferometric readout. The heterodyne interferometer is completely fiber based with a 1064 nm diode laser source and has a subpicometer resolution at 1 Hz. We present and discuss the design and the characterization of the interferometer, the foreseen performances of the whole accelerometer and the characterization strategies of the same.

Abstract
Accelerometers for space applications are typically based on a capacitive readout. Here we present the design of an accelerometer based on a classical mass spring mechanical system with an interferometric readout. The heterodyne interferometer is completely fiber based with a 1064 nm diode laser source and has a subpicometer resolution at 1 Hz. We present and discuss the design and the characterization of the interferometer, the foreseen performances of the whole accelerometer and the characterization strategies of the same.| File | Dimensione | Formato | |
