To demonstrate Snapscan’s capabilities in life sciences, medical applications and diagnostics, three experiments have been conducted. First, Snapscan was used to image a hand with one finger tied with a rubber band. The blue spectra image corresponds to the finger with a restricted blood flow, whilst the red spectra shows a normally oxygenated one. While hardly any difference between both fingers can be noted with the naked eye, the hyperspectral curves show a clear distinction in their hyperspectral response (related to the presence of oxygenated vs. deoxygenated blood). This shows the added value of Snapscan to monitor wound healing, or in surgery (for real-time follow-up on the condition of the organs), where oxygenation is essential. Next, a blood smear was imaged by attaching Snapscan to an optical port of a microscope, detailing fine structures in the sample. This proves Snapscan’s worth in microscopy applications, and for automatic counting or identification of certain types of cells. Finally, a set of six types of medical pills was imaged. Whereas some pills could not be differentiated through RGB imaging, the hyperspectral curves in the NIR spectrum made this possible – confirming the camera’s relevance in the pharmaceutical industry for pill inspection.
