A 32×32 Pixel 0.46-to-0.75THz Light-Field Camera SoC in 0.13μm CMOS
Light-field (LF) refers to the spatio-directional light flow in space. In LF imaging, light rays are recorded along different positions and directions, and a 3-D scene is reconstructed with back-propagation [1]. Modern visible-light LF cameras assemble a lens array atop a megapixel (Mpx) count focal-plane…

Incoherent, spatially-mapped THz spectral analysis
We employ a lens-coupled CMOS terahertz camera to measure the dispersion of an inexpensive reflective diffraction grating. Thus, although the terahertz camera was originally intended for terahertz imaging applications, we show that it can be re-purposed to perform spectral analysis. Two different experiments…

Terahertz spectroscope using CMOS camera and dispersive optics
There is a need to reduce the cost and size of functional terahertz devices, in order to expedite this notoriously under-utilized frequency band toward practical applications. Electronic integrated circuits (ICs) are extremely useful to this end, as they provide a means to achieve miniaturization and…

A 64-Pixel 0.42 THz Source SoC with Spatial Modulation Diversity for Computational Imaging
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…
