Displacement Follower User’s M anual Version 1.4, April 19, 2004 IM1008 Page 3 Theory of Operation The system is a non-contacting electro-optical displacem ent follow er desig ned to track the motion of a target along any axis . The moving target under study m ust show a sharp discontinuity in the inten sity of its reflected o r emitted light.
Displacement Follower User’s M anual Version 1.4, April 19, 2004 IM1008 Page 4 There are two possible target config urations for meas uring target displacemen t alon g the vertical axis: light over dark and dar k over light.

Its equivalent position is, in fact, approximately 13mm f urther along the optical axis than the position used in the calculations.
Displacement Follower User’s M anual Version 1.4, April 19, 2004 IM1008 Page 9 Ta r g e t i n g Target Requir ements The 5000 Series operates by locking onto a sharp discontinu ity in the intensity of an obj ect’s reflected or em itted light.

For high light conditions, the high voltage may be r educed, or neutral density filters can be placed in fron t of the lenses. Note The light source must be DC o r the tracker will detect the 60 Hz chan ge in light intensity.
