Årskurs: F-3, 4-6 Ämnesområde: Ljus och ljud Med hjälp av så kallade UV-pärlor kan man testa hur effektiva olika solskydd är. Vi kan inte se solens ultravioletta strålar (UV-strålar) men vi märker att de finns där eftersom vi blir solbrända. Med UV-pärlor kan man direkt avgöra var UV-strålarna finns, och hur man skyddar sig mot dem på bästa sätt. Material Två eller flera olika sorters solkräm. En

Årskurs: 4-6, 7-9 Ämnesområde: Ljus och ljud Ögats näthinna reagerar på det ljus som kommer in i ögat. Näthinnan skickar signaler till hjärnan, detta är att se. Det finns emellertid delar av näthinnan som inte ger dig någon syninformation. Detta är ögats blinda fläck. Med hjälp av nedanstående experiment kan du räkna ut storleken på den blinda fläcken, visa att den finns och hur hjärnan kompense

Photoacoustic imaging is one of the most promising non-invasive biomedical imaging techniques. It combines laser light and ultrasound to generate high resolution 3D images (resolution 15–40 μm, 2 cm depth) of the tissue structure and molecular composition. The analyzed tissue is irradiated with pulsed laser light, which causes so-called thermoelastic expansion, which in turn generates mechanical w

Diffuse reflectance spectroscopy (DRS) utilizes white light with a known spectrum, which is guided to the surface of the skin via an optical fiber. As light penetrates into the tissue, photons either scatter or become absorbed where only a fraction of the injected photons manage to escape back from the skin surface. This light is captured by a second fiber and measured with a spectrometer. Dependi

This project focuses on evaluating novel imaging techniques for measurement of perfusion and oxygenation in the anterior segment of the eye and the eye muscles during strabismus surgery. By doing this, the risk of anterior ischemia could be calculated and surgical techniques optimized. Strabismus is a state of impaired ocular alignment with a prevalence of 2-4% in the western world. In children, s

Unsupervised skin tumour delineation using hyperspectral imaging and machine learning. Hyperspectral imaging provides detailed spectral and spatial information of a surface in ways our eyes are not capable of visualizing. We use a custom-made hyperspectral imaging camera from Norsk Elektro Optikk (NEO), capable of providing spectral information between 400-1700 nm. While this allows us to produce

We have a Teledyne FLIR A655sc camera for highly resolved thermal imaging, which allows for non-invasive temperature mapping of tissue. This enables direct feedback of the potentially damaging effects of absorbing too much laser light, which is important for setting guidelines for safe clinical implementation of PAI. Thermal imaging is also useful as a complementary monitoring system for a range o

Spectral coloring is a phenomenon that becomes relevant when studying light of different “colors” (wavelengths) propagating through tissue. It is expected that light gets attenuated as it reaches further into the tissue. However, since the absorbing species in the tissue interact with different wavelengths, the spectrum of light that remains to be absorbed at deeper layers will change shape and th

Amyloidosis is a rare disease characterized by a buildup of abnormal amyloid deposits in the body. Amyloid deposits can build up in the heart, brain, kidneys, spleen and other parts of the body. Amyloid in the heart reduces the ability to fill with blood between heartbeats. Less blood is pumped with each beat, and the patient experience shortness of breath. If amyloidosis affects your heart's ele
