Parameter Study of Statistics of Modal Parameter Estimates Using Automated Operational Modal Analysis [PDF]
For any modal parameter estimation (MPE) method, there are a few control inputs that can have an impact on the modal parameter estimates. These control inputs are typically involving parameters like the maximum model order and how many time values or frequency lines that should be included in the MPE.

Distributed Parameter Modal Sensors.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996 This paper deals with distributed parameter sensors designed with a view to extracting a vibration mode. Compared to conventional point-type sensors such as acceleration pickups, displacement sensors etc., the distributed parameter sensors have many benefits provided that they are properly designed.
