As an extension of Synthetic Aperture Radar Interferometry, Multiple Aperture Radar (MAI) is a spectral diversity technique that allows the determination of azimuth displacements from phase shift measurements. This is made possible through the creati

We propose a new inverse-problem-based reconstruction technique to off-axis THz digital holography. The proposed method takes into account the non-uniformity of the reference wavefront and reconstructs the object field as well as the amplitude of the

We apply an inverse-problem-based reconstruction technique to off-axis THz digital holography. Off-axis digital holography configuration at THz regime suffers from non-ideal recording conditions due to the large wavelength. The proposed method takes

In terahertz digital holography, the off-axis configuration is the appropriate choice when the investigated object is non-sparse and complex. The limitation of recording distance in the off-axis configuration restricts the imaging quality. Either low

The intrinsic resolution of 2.52 THz off-axis digital holography system is known to be diffraction limited. However, in practical recording condition, reference wavefront would inevitably suffer excessive diffraction or obstruction with large off-axi

Speckle shearing interferometry (shearography) is a full-field strain measurement technique that can be used in vibration analysis. In our case, we apply a method that combines the time-averaging and phase-shifting techniques. It produces binary phas

Locating defects in CFRP composite materials is a hot topic in nondestructive inspection (NDI). Beside classical NDI technique, such as ultrasound testing (UT), contactless techniques are actively studied. Generally manufacturers of CFRP structure in

EEG signals are often contaminated by ocular artifacts (OAs), in particular when they are recorded for a subject that is, in principle, awake, such as in a study of drowsiness. It is generally desirable to detect and/or correct these OAs before inter
