Ptychography Reconstruction

This notebook demonstrates a simulated ptychographic reconstruction using tike.

import logging

import matplotlib.pyplot as plt
import numpy as np

import tike
import tike.ptycho
import tike.view

for module in [tike, np]:
    print("{} is version {}".format(module.__name__, module.__version__))

tike is version 0.15.2.dev39+g7ca618d.d20210126
numpy is version 1.19.5

Load test data

This data was simulated using tike and it used for continuous integration testing.

import lzma
import pickle

with lzma.open('../../../tests/data/ptycho_setup.pickle.lzma', 'rb') as file:
    [
        data,
        scan,
        probe,
        original,
    ] = pickle.load(file)

Define the object

The object consists of two unique views of varying phase: one with constant amplitude and one with varying amplitude.

original.shape

(2, 128, 128)

# Center the phase image in the range (-pi, pi)
original = original * np.exp(-1j * np.pi/2)

for i in range(len(original)):
    plt.figure()
    tike.view.plot_phase(original[i], amax=1, amin=0)
    plt.show()

(0.001338858+0.9999991j) (1+0.00020559915j)

(0.00013624692+5.2331194e-05j) (0.9566685+0.0636505j)

Define the probe

Note that the shape of the probe includes many dimensions. These dimensions are for providing multiple incoherent probes and coherent probbes along with unique probes for multiple dimensions. Read the documentation of the tike.ptycho.probe module for more information.

probe.shape

(2, 1, 1, 2, 16, 16)

probe *= 5 # reduce noise

for m in range(probe.shape[-3]):
    plt.figure()
    tike.view.plot_phase(probe[0, 0, 0, m])
    plt.show()

(-3.146963+3.8854375j) (4.9999995+0.0015707964j)

/home/dching/Documents/tike/src/tike/view.py:95: UserWarning: This phase plot will be incorrect because the phase of a zero-amplitude complex number is undefined. Adding a small constant to the amplitude may help.
  "This phase plot will be incorrect because "

(-2.4711988+0.3783875j) (2.4927204+0.19064504j)

Information about a probe which varies with each scanning position is stored in the weights and coherent_probe arrays.

# Add some probe variance
np.random.seed(0)
true_coherent_probe = probe
weights = 0.25 * tike.ptycho.probe.simulate_varying_weights(scan, true_coherent_probe)
true_probe = tike.ptycho.probe.get_varying_probe(probe, eigen_probe=true_coherent_probe, weights=weights)

plt.figure()
plt.plot(weights[0, :, 0, 0])
plt.plot(weights[0, :, 0, 1])

[<matplotlib.lines.Line2D at 0x7f23b95e8950>]

Define the trajectory

Each view may have a different trajectory, but the number of scan positions must be the same. The probe positions that overlap the edge of psi are not allowed.

scan.shape

(2, 169, 2)

# Add some position noise
np.random.seed(0)
true_scan = scan + 1 * (2 * np.random.rand(*scan.shape) - 1)

plt.figure()
plt.scatter(true_scan[0, :, 0], true_scan[0, :, 1])
plt.axis('equal')
plt.show()

Simulate data acquisition

# Then what we see at the detector is the wave propagation
# of the near field wavefront
data = tike.ptycho.simulate(detector_shape=probe.shape[-1] * 2,
                            probe=true_probe, scan=true_scan,
                            psi=original)
data.shape

(2, 169, 32, 32)

np.random.seed(0)
data = np.random.poisson(data)

plt.figure()
plt.imshow(np.fft.fftshift(np.log(data[0, 11])))
plt.colorbar()
plt.show()
np.min(data), np.max(data)

Reconstruct

Now we need to try and reconstruct psi.

coherent_probe, weights = tike.ptycho.probe.init_varying_probe(scan, probe, 1)

coherent_probe.shape, weights.shape

((2, 1, 1, 2, 16, 16), (2, 169, 1, 2))

# Provide initial guesses for parameters that are updated
np.random.seed(0)
result = {
    'psi': np.ones(original.shape, dtype='complex64'),
    'probe': probe * np.random.rand(*probe.shape),
    'scan': scan,
    'eigen_probe': coherent_probe,
    'eigen_weights': weights,
}

logging.basicConfig(level=logging.INFO)
