Abstract
An optical accelerometer arrangement (20) comprises an array of optical accelerometers (26) attached to a common structure (22). Each of the optical accelerometers (26) provides a signal indicative of displacement of a measurement mass (6) as a result of an acceleration along a given axis applied to the common structure (22). The arrangement (20) also comprises a processor (31a) configured to determine an estimate of the acceleration using the signals provided by the accelerometers (26). The arrangement (20) may be attached to an object (40; 46; 0; 52) which also comprises a gyroscope (44) and/or a camera (48).

-18. (canceled)
An object comprising a gyroscope providing a gyroscope signal and an optical accelerometer arrangement comprising:
- an array of optical accelerometers attached to a common structure, each optical accelerometer of said array of optical accelerometers providing a signal indicative of displacement of a measurement mass as a result of an acceleration along a given axis applied to the common structure;
- and
- a processor configured to determine an estimate of said acceleration using said signals from said array of optical accelerometers.
A mobile object comprising:
- an array of optical accelerometers attached to a common structure, each optical accelerometer of said array of optical accelerometers providing a signal indicative of displacement of a measurement mass as a result of an acceleration along a given axis applied to the common structure;
- a camera;
- and
- a processor configured to determine an estimate of position of the mobile object using said array of optical accelerometers and said camera.
