The research team is focused on the development of a chip-sized spectroscopy microsystem for the detection of gastrointestinal (GI) early cancerous lesions. The paper will briefly cover the outstanding properties of diffuse reflectance and fluorescence spectroscopy detection and the concept of cointegration of highly selective thin-films optical interference filters on silicon photodiodes, in order...
This paper describes the design of a miniature, cost-effective spectroscopy system for assessing tissue biochemical and morphological information using a few wavelengths. This instrument will integrate thin-film optical filters and silicon photodiodes, avoiding the use of a spectrograph and optical fibers. The components in the set-up design are described. The feasibility of using only 16 wavelengths...
