Converting the Transient Newton Rings into Equivalent Depth Profile using Image Processing Technique

Amit Pratap Singh


Transient newton rings that are formed in laser ab- lated surface provides a useful tool to understand the mechanism of ultrafast laser induced micro-processing. There are different kind of technique available which are capable to study the evolution of ablation morphology through transient newton rings. The purpose of this research work is to develop a novel technique that does not require the real time evaluation. The proposed approach uses image processing technique that converts transient newton rings images into the array of two dimensional data. These datas are further reconfigure to produce equivalent depth profile. The equivalent depth profile of time resolved newton rings image can be used to study the evolution of morphological features created by laser ablation.
