Millimetre wave radiation can be used to see inside objects and reveal hidden information. Improving the performance of millimetre wave illuminators and detectors while keeping the devices compact has proven to be challenging. Dr Pranith Byreddy and Dr Kenneth O at The University of Texas at Dallas, USA and Dr Wooyeol Choi at Seoul National University, Korea have developed pixels including an illuminator and detector with improved sensitivities as well as a lensless imager using these pixels.

The electromagnetic waves at frequencies ranging from 0.1 to 10 THz have shown to hold promise for a wide variety of security [1], industrial [2], medical imaging [3], and other everyday life applications [4], [5]. At 0.1 to 1 THz, the waves can be used to capture images in visibly impaired conditions such as fog, rain, dust, and others [6], [7], [8], as well as through packaging and other materials.
