Abstract

Spatial frequency domain imaging (SFDI) is a wide-field imaging technique that provides quantitative tissue optical property maps. We describe a compact, multi-aperture SFDI imager for burn severity evaluation. This was constructed using a CMOS sensor subdivided into multiple regions, each having a bandpass filter and objective lens. This compound-eye design enables simultaneous image acquisition at multiple wavelengths. The imager was evaluated using a rat burn model and compared to conventional SFDI devices that acquire wavelength data sequentially. The burns showed a decrease in the reduced scattering coefficient that is consistent with previously reported changes in full thickness burns.
