Tracking Filter

Function

The tracking filter can be used to improve the signal-to-noise ratio of the

signal from the scanning head. This filter bridges brief dropouts. These

dropouts occur due to the speckle nature of the light scattered back from the

object. Thus the tracking filter increases the optical sensitivity of the

vibrometer.

There are four tracking filter settings available:

Slow

Medium

Fast

, and

Off

With the

Off

setting you can switch off the tracking filter.

The different tracking filters have different maximum accelerations. The lower

the maximum acceleration, the higher the optical sensitivity.

With the

Fast

setting, the tracking filter is always adjusted to the highest

possible acceleration values that result from the bandwidth set and the

selected measurement range. Thus, the

Fast

setting is suitable for all

velocities and frequencies that may occur within the measurement range.

With the

Medium

setting, the tracking filter is optimized for a maximum

acceleration of 10% of the

Fast

setting. If the acceleration does not exceed

this value, the

Medium

setting has a better effect than

Fast

. It is suitable for

noise excitations, as generally in this case the maximum accelerations of the

measurement ranges are not fully used.

With the

Slow

setting, the tracking filter is optimized for a maximum

acceleration of 1% of the

Fast

setting. This setting is suitable if the velocity

range is nearly saturated by a low-frequency distortion and at the same time

the actual high-frequency wanted signal only has a low amplitude. This is

particularly the case with measurements on rotating parts. The

Slow

setting

has the highest optical sensitivity.

Cutoff

frequencies

In addition, the different tracking filter settings are designed for different cutoff

frequencies.

The tracking filter can also be used for bandwidths that exceed the respective

cutoff frequencies of

Slow

Medium

, and

Fast

. This is particularly useful for

measurements in the time domain as in this case, to obtain a better time

resolution, you often select a higher bandwidth than it would be required by

the signals. Signal components above the respective cutoff frequency are

damped with 15…30 dB/decade.
