In this paper, a silicon lens-integrated CMOS THz camera is employed as a compact antenna test range. The far-field radiation pattern of a 26-dBi 0.852-THz standard gain horn antenna radiation source is characterized. Both single-frame low-resolution and multi-frame super-resolution acquisition are performed.…

Integrated THz systems comprising index matched optical media introduce discontinuities in the propagation path leading to an etaloning effect. The etaloning hinders the absolute accuracy of a measuring instrument thereby limiting its applicability. A methodology using computational notch filtering is…

In this paper, we present a comprehensive study to understand the image formation and associated resolution limitations of hyper-hemispherical high-resistivity floating-zone silicon (HRFZ-Si) lens-integrated terahertz (THz) cameras, and we extend this understanding into THz super-resolution imaging applications.…

This paper presents a terahertz source system-on-a-chip (SoC) specifically designed for computational imaging with a single pixel camera (SPC). The SoC consists of an 8×8 array of independent, frequency unlocked THz sources that together radiate maximum 10.3 dBm power at 0.42 THz. Each source pixel is…

Decoupling the desired spectral signal from scattering events and also from the sporadic signals from the background has been a challenge for fulfilling the promise of real-time applications exhibited by the present broadband terahertz devices. Performing imaging in conjunction with spectroscopy will…
