3 Oxford contributions to IWAA 2002 Frequency Scanning Interferometry in detail P. A. Coe et al (This presentation) Multiple, simultaneous length measurements S. M. Gibson et al (After the next presentation) Combination of FSI with other novel optical tools A. Mitra et al (Final presentation of IWAA 2002)
Frequency Scanning Interferometry Motivation : Want to be able to - • Measure any length (range 60 mm to 1.5 m) to 1mm • Measure inside ATLAS tracker during operation • High radiation and low temperature -20 deg C no access, have to measure remotely • Very little space : • Components inside ATLAS must be low mass • Must be maintenance free for 10 yr ATLAS lifetime AND…
Motivation : … we want to make … 800 length measurements simultaneously!
