Seminarium Optyczne

In recent years, the increased research has been conducted in the field of terahertz (THz) optics and imaging. The description that explores the landscape of THz optics, focusing on its achievements, current challenges, and prospects is given in this lecture. THz radiation, characterized by wavelengths considerably longer than visible light, induces substantial diffraction effects, profoundly impacting its behavior and imaging capabilities with optical elements. Moreover, the high coherence exhibited by various THz sources facilitates precise wave manipulation. However, it also introduces unwanted interference effects, which are challenging to suppress. Moreover, in many cases, THz optical systems operate within the near-field diffraction zone, which has its peculiarities.The advancement of THz optics is closely related to exploring various materials and manufacturing techniques. Different materials, ranging from dielectrics to semiconductors, exhibit excellent optical properties in the THz range. Furthermore, innovative manufacturing methods such as lithography, additive manufacturing, and metamaterial engineering play crucial roles in developing novel THz optics.This lecture highlights various achievements, current challenges, and promising avenues in the field of THz optics. Emphasizing its versatile applications and the role of material science and manufacturing innovation underscores the transformative potential of THz technology in shaping future advancements.
