A 0.1 Megapixel THz camera with 17 degree field of view for large area single shot imaging

Large area THz video-rate imaging is demonstrated using a 0.1 Megapixel THz camera having a 17 degree Field of View and 50 Hz frame rate. Active THz see-through imaging has been performed where the THz laser beam has been expanded using a series of custom lenses. Owing to the quality of the beam expansion set-up and good sensitivity of the IRXCAM-THz-384 camera, high quality, large area THz images are possible, opening the door to fast screening applications in fields such a Defense & Security and Manufacturing.

I. Introduction

TERAHERTZ (THz) imaging is a very promising field rapidly growing in importance. This expanding field is at its early stage of development but already a large number of applications are foreseen. The ability of THz to see through objects promises to make THz a key technology in various fields, such a Defense & Security and Manufacturing.
