abstract = {Significance: There is a need for a cost-effective, quantitative 

 imaging tool that can be deployed endoscopically to better 

 detect early stage gastrointestinal cancers. Spatial frequency 

 domain imaging (SFDI) is a low-cost imaging technique that 

 produces near-real time, quantitative maps of absorption and 

 reduced scattering coefficients, but most implementations are 

 bulky and suitable only for use outside the body. Aim: We aim to 

 develop an ultra-miniature SFDI system comprising an optical 

 fiber array (diameter 0.125 mm) and a micro camera (1$times$1 

 mm package) to displace conventionally bulky components, in 

 particular, the projector. Approach: First, we fabricated a 

 prototype with an outer diameter of 3 mm, although the 

 individual component dimensions could permit future packaging to 

 a 90% are feasible for detecting simulated squamous cell 

 carcinoma. Conclusions: This device shows promise as a 

 cost-effective, quantitative imaging tool to detect variations 

 in optical absorption and scattering as indicators of cancer.},
