Liquid crystal experiment for undergraduate engineering students
Author(s): Mansoor B. A. Jalil

Paper Abstract

An undergraduate experiment to investigate the optical properties of liquid crystals (LC) is described. The target students are final-year undergraduates pursuing an advanced optoelectronics course at the Electrical and Computer Engineering Department of the National University of Singapore. In the first part of the experiment, the retardation of light by a LC cell is determined by analyzing the polarization state of light passing through the cell. In the second part, the time response of the LC molecules is obtained by applying a time -varying voltage to the LC cell. The objectives of the experiment are to i) provide a hands-on experience of an optical source-modulator-detector system, in response to the needs of industry, ii) illustrate a practical application of Jones matrix analysis, iii) establish a link between the molecular properties of an LC medium and their optical properties and iv) show how the material properties of a LC material may influence its use in display devices.
