Analyzing the structure of solar coronal loops is crucial to our understanding of the processes that heat and maintain the coronal plasma at multimillion degree temperatures. The determination of the physical parameters of coronal loops remains both an observational and theoretical challenge. A novel diagnostic technique for quiescent coronal loops based on the analysis of power spectra of Doppler-shift time series is developed and proposed to test on real data.

We point out that the analysis of the power spectra allows distinction between uniformly heated loops from loops heated near their footpoints. We also argue that it becomes possible to estimate the average energy of a single heating event.

Through examples of synthetic and direct SoHO/SUMER and Hinode/EIS observations of waves, the applicability of the method is demonstrated successfully.
