Simple examples

Here is a simple example on how to use the code:

import pyLIA
import numpy as np
import matplotlib.pyplot as plt

data = np.load('camera.npy') ## Thermal acquisition
fs = 400  ## Sampling freqency of the thermal video [Hz]
fl = 55  ## Load freqency of the excitation test [Hz]

mag, ph = pyLIA.LIA(data, fs, fl)

plt.figure()
plt.imshow(mag)
cbar = plt.colorbar()
cbar.set_label('[unit]')

plt.figure()
plt.imshow(ph)
cbar = plt.colorbar()
cbar.set_label('[deg]')
