Hyperimager: A compact multi-spectral imaging platform
Imaging technologies are an essential part of healthcare, quality assurance, science, and daily life in
general. Sensors and devices that allow us to obtain information or “see” outside of the visible spectrum,
such as a thermal camera or an X-ray camera, have become increasingly available over the last few
Multi-spectral imaging consists of looking at a scene at distinct portions of the electromagnetic spectrum
to gain information/insights otherwise unavailable or with more accuracy than using a single wavelength.
Hyperspectral imagers present in airborne platforms and satellites have shown the vast possibilities
arising from imaging a scene over a broad range of wavelengths, mainly for geospatial applications.
Inspired by the capabilities of hyperspectral imagers, and motivated by the increasing availability of
silicon-based sensors for multiple wavelengths (mmWave, THz, infrared, visible domain, etc), IBM
Research has developed a portable multi-spectral imaging device (Hyperimager) consisting of a mmWave
phased array coupled to radar signal processing, an IR camera, and a visible domain camera. This talk
will present the the hyperimager architecture, the associate Si-based mmWave radar imaging sensor, and
initial multi-spectral imaging results.
