The FOCISTM system comes loaded with a software suite for test setup, real-time data collection and vibration monitoring, and post-processing analysis.
FOCISTM software allows precise configuration of each rotor stage, setup of the probes and control of their function (blade tip timing, blade tip clearance, or both) through a graphical interface.

Choose the best placement of the optical probes around the rotor based on the vibration modes of interest with the Circumferential Optimizer.

Signal Monitoring and Adjustment
The FOCISTM software enables verification of probe operation, and verification of the signals collected via a graphical interface ("digital oscilloscope").

Test operators can adjust laser power and channel gain through software.

FOCISTM software can output clearance measurement as average of all blades or blade-by-blade. Minimum, maximum, and average clearance is available.

Blade Tip Timing and Vibration Analysis
The FOCISTM software suite includes real-time and post-processing blade vibration software.
Real-Time Blade Vibration Software
DAQ+ is the real-time blade vibration software for test monitoring and visualization of blade vibration in real time.

BT is the post-processing software for deep analysis of blade vibration events, both synchronous and asynchronous.

Generate Plots of Recorded Parameters
- Relative & Absolute blade position
- Deflection (including automatic determination of deflection based on polynomial curve fit to remove the static blade position)
- History, Campbell, and Waterfall plots are available
- Asynchronous analysis
- All blades FFT
- Identification of nodal diameter response and flutter events
- Frequency, magnitude & phase for the stage
- Synchronous analysis:
- Identify responding engine orders via sine wave fit for all probes on a per rev basis
- Frequency, magnitude & phase for all blades
