An accelerometer device configured for in-situ calibration applies a laser-induced pushing force at a first magnitude to a proof mass of an accelerometer, and while applying the laser-induced pushing force at the first magnitude to the proof mass, the device obtains a first output from the accelerometer. The device is further configured to apply a laser-induced pushing force at a second magnitude to the proof mass, and while applying the laser-induced pushing force at the second magnitude to the proof mass, the device obtains a second output from the accelerometer. Based on the first output and the second output, the device determines a scale factor for the accelerometer. The device is configured to determine a third output for the accelerometer, and based on the scale factor and the third output, determine an acceleration value. |
