thus, this VI can generate a graph of light intensities in term of the translated distances and save it to a log file.
3. another NI LabVIEW's VI was developed to analyze the data from step 2 in the following procedures:
3.1 trimming the edges of the graph which are usually unstable
3.2 finding the translated length of the trimmed portion of the graph
3.3 counting the peaks of the graph which in turn equal to the shifting of the fringes
3.4 calculating the estimated wavelength using the equation
