In this contribution we optimize THz-spatial modulator design, post-processing algorithms and undersampling methods with the aim of minimizing the acquisition of a THz-image using a single-pixel detector and being able to display the image without needing long computational times. Further, we investigate how to synchronize the optical delay line so as to obtain a THz image containing time-of-flight information and then demonstrate that neural networks can improve image quality in real-time.
