An optical gyro rotating at very less velocity may generate an output signal in milliHertz range. Is it possible to detect such signals?
Dear Arpit,
From the electronics circuit design point of view, it is perfectly well possible to detect milli-Herz frequency range signals. The big question is more how stable and drift free the gyro sensor itself is in te zero condition where the to be detected signal is not present. With gyro signals over a prolonged period, one has to account for the rotation of the earth as well. One might also use the earth rotation signal as a trick to zero a pair of mirrored gyros.
Temperature drift compensation seems anyhow a good measure.
Hope this helps.
1000 s is about 16 minutes. 1,000,000 s is about 12 days. You'll need to have several periods to ensure that this is really the frequency. To make it a signal you'll need to start and stop it.
The measurement time is few days. It's need that the measurement process is repeated several times.
