In this communication, we consider principles of design and assembling of nonparaxial THz imaging systems based on silicon diffractive optics components. The investigation is dedicated to lensless photonic setups comprising high-resistivity silicon-based DOEs such as Fresnel zone plates, Fibonacci lenses, Bessel axicons, and Airy zone plates, all fabricated from a high-resistance 500 μm thick silicon substrate by femtosecond laser ablation. The exploration underlines the significance of structuring both the illumination and light-collection schemes as well as assembly principles of silicon diffractive optical elements in compact THz imaging.
