  A Free Elec­tron Laser os­cil­la­tor with ra­di­a­tion wave­length 50–100 μm is under con­struc­tion in Huazhong Uni­ver­sity of Sci­ence and Tech­nol­ogy (HUST). The lin­ear po­lar­iza­tion un­du­la­tor with K=1.0-1.25 has been de­signed and man­u­fac­tured by Kyma s.r.l., by using a pure per­ma­nent mag­net scheme. Ac­cep­tance test bas been per­formed in Kyma fac­tory with well con­trolled phase error and field in­te­grals for all gaps. This paper in­tro­duces the de­vel­op­ment of an on­line field in­te­grals mea­sure­ment sys­tem for the un­du­la­tor, using the stretched wire method. The de­sign and con­sid­er­a­tions of the op­ti­cal align­ment sys­tem is de­scribed as well.
