Imaging at terahertz frequencies (0.1-10 THz, wavelengths 3 mm-30 µm) has proven to be useful in the biomedical field. Still, the acquisition time is an important hurdle. Here, we discuss recent developments toward achieving real-time THz imaging. First, we demonstrate a spectral encoding algorithm to reconstruct a 4500-pixels image with 45 measurements. Second, we improve the image resolution using a super-resolution algorithm specifically developed for the THz. Third, we discuss our most recent work on the fabrication of an THz photoconductive antenna array for imaging. These works pave the way for future applications of THz imaging in biomedical science.
