説明

In the fundamental research of optical materials, it has been necessary to measure their polarized functions. Especially, a little birefringence in the ultra thin film such as Langmuir-Brodgett film and its dynamic characteristics such as liquid crystal have not had clearly data and many discussions. Therefore, we are developing a high sensitive measurement system of dynamic birefringence using optical phase modulator (Pockels device) and two Faraday rotators (Faraday device). This report describes some basic workings of the new high sensitive measurement system. It was possible to measure a small birefringence (retardation 5×10^-3 rad) and fast axis angle of sample.
