The structural influence coefficients for an imaging optical system map the decenter and tilt motions of the system elements to changes in the direction and orientation of the line-of-sight and image. A methodology is presented to calculate the structural influence coefficients for the lenses of long-focus (near-infinity) imaging optical systems. Single-lens systems are considered first, with the method then extended to handle multiple elements. Use of an arbitrary structural reference frame is discussed, along with an algorithmic, recursive approach to numerical calculation of the structural influence coefficients. A complete derivation is presented at each step, and an overview of the geometric optical principles involved is provided for reference. The method described allows ready calculation of influence coefficients without tedious ray-trace perturbations or dedicated optical analysis software. This paper is a companion to a previous paper by the authors, in which the structural influence coefficients for plane-mirror systems are derived. The influence coefficient method of both papers is unique in its use of line-of-sight reference frames as an optical kinematic tool to track pointing direction and image orientation.
