High Throughput Dual-Band Infrared Hyperspectral Imaging for Contraband Detection

Spectrum seeks to develop a compact, dual-band infrared hyperspectral imaging capability for high-throughput detection of contraband at Customs and Border Patrol (CBP) Points of Entry (POE).Fourier Transform Infrared FTIR spectroscopy is a proven laboratory technique for material identification.In particular, the long wave infrared (LWIR) wavelength range is rich with exploitable phenomenology due to its positions in the heart of the fingerprint region of infrared spectra.Laboratory FTIR spectrometers are inherently low throughput, however companies such as Spectrum Photonics are focused on adapting FTIR technology for high throughput applications.One such technique is active IR hyperspectral imaging (HSI), wherein the single pixel (point) detectors are replaced by imaging arrays.This allows for a dramatic increase in throughput relative to single pixel laboratory FTIR technology.Spectrum has demonstrated the simultaneous acquisition of hundreds of thousands of unique infrared spectra per second.Spectrum Photonics seeks to adapt our compact high-speed spectral imaging capability to develop a portable, high throughput screening capability for the detection of contraband at CBP POE.
