Abstract: At the Institute of Atomic Physics and Spectroscopy of University of Latvia multiple optical technologies are being developed for biomedical applications. One such area is assessment of cutaneous manifestations in patients with rare diseases, which are diseases that affect less than 1 in 2000 individuals. There are various rare diseases that are systematic multi-organ diseases that can remain undiagnosed for many years but may have symptoms appearing on the skin, at early stages easily mistaken for more common skin diseases. In our studies we have looked at angiokeratomas caused by Fabry disease, café-au-lait macules and neurofibromas caused by Neurofibromatosis Type 1, lesions caused by Leprosy and others using multispectral imaging and spectroscopy. Another area of research in our institute is laser speckle imaging of microbial growth. Laser speckles are an interference pattern that forms when a laser beam scatters off different parts of an uneven surface. This property allows imaging the movement of very small objects such as bacteria and fungi. In our studies we have experimented with bacteria such as Pleurotus ostreatus, Escherichia coli and others. We hope to achieve near-real-time monitoring of bacterial growth using this technology.
