Abstract

Optical disc birefringence affects playback performance in a variety of ways and is routinely measured as part of the manufacturing process. However, many disc manufacturers have observed significant variation in birefringence measurements when using commercially available instrumentation. To quantify the reliability of these tools, the Optical Disc Manufacturing Association (ODMA) and NIST performed a round robin intercomparison of optical disc retardance measurements. In this paper, we report that remarkably large measurement variation among instruments indeed exists. We discuss some sources of this variation to show that a substantial part is due to instrument uncertainty, and describe possible error source in one class of polarimetric instruments.
