Real-time visualization of the photorefractive effect via single-pixel complex-amplitude imaging - Dataset 1

A 532 nm Gaussian beam locally pumps the LiNbO₃:Fe crystal while 632.8 nm uniform illumination probes the induced refractive index modulation. These four <i>npz</i> data files contain amplitude and phase image data acquired by single-pixel complex amplitude imaging for pumping and probing with horizontal and vertical linear polarization, respectively. They also include unwrapped phase image data and refractive changes image data. The <i>Data-Show</i> file is a Python script used to display the npz data.<br><br>
