Paper Abstract

Measurements of very small phase changes in optics are usually performed by interferometric methods on the basis of evaluation of interference patterns that corresponds to a specific phase change of the investigated wave field. If values of the phase change are small, it is difficult to evaluate accurately the phase values, and one needs a very expensive measurement systems. Our work describes a simple method for evaluation of small phase variations that uses the interference of polychromatic light. The phase change has effect on the colour of the interference pattern. Every colour of the interference pattern can be assigned to a specific phase change and it can be evaluated using colorimetric methods, The proposed method offers very accurate results and it is suitable for practical utilization in optical industry due to its simplicity.
