Characterizing periodicity level of signal after two-dimensional Fourier transform

I have a sequence of vectors, each of them is an 88-dimensional vector. For example, [0, 0, 0, 1, 0,....]. I want to measure whether this sequence has periodicity, and I have used 2-dimensional Fourier Transform.
How to visualize this periodicity?
How to measure the periodicity, such as a scalar. Better the periodicity, more the value.
