In a prior paper, we described a new imaging architecture that addresses the need for wide field-of-view imaging combined with the resolution required to identify targets at long range. Over the last two years substantive improvements have been made

Coded aperture spectroscopy allows for sources of large etendue to be efficiently coupled into dispersive spectrometers by replacing the traditional input slit with a patterned mask. We describe a coded aperture spectrometer optimized for Raman spect

Time-series whole-body microphotography may potentially be used for diagnosing skin disease, telemedicine, surgical field registration, and epidemiological studies. We demonstrate the technology by imaging a volunteer at 0.25 gigapixel resolution in

Computational Imaging holds great promise for improvement in performance, along with significant reductions size weight, and power (SWaP). In pursuit of this potential, Raytheon has for the past several years conducted an internally funded research e

Raman signal estimation in highly fluorescent media is investigated using multiple excitation lasers and an iterative EM spectral reconstruction algorithm. Results from an 8-laser system show estimation performance increases with the number of excita

We have designed and constructed a multimodal multiplex Raman spectrometer which uses multi-wavelength excitation to better detect signals in the presence of fluorescence by taking advantage of the shift-variance of the Raman signal with respect to e

Raman spectroscopy of bulk tissue is challenging due to sample auto-fluorescence and weak Raman cross-sections of most molecules. We investigate the use of coded-excitation Raman spectroscopy coupled with an iterative algorithm for Raman signal estim
