title: Calibration of three-dimensional eye position using search coil signals in the rhesus monkey.
abstract: A procedure is described to calibrate three-dimensional eye position with a dual-search coil implant in rhesus monkeys using a two-field magnetic system. The method allows one to determine the sensitivity of the search coils taking into account the presence of d.c. offset voltages. The orientation of the implant on the eye relative to a space-fixed reference frame is computed using fixations of targets arranged vertically. The critical steps of the procedure are discussed and documented by experimental data.
