How does the new technology work?
The new technology sPROPT makes use of light of varying intensity using inexpensive light sources. The targeted medium absorbs the light by relevant absorbers, such as hemoglobin, melanin, dyes, particles, and black carbon. The absorbers generate ultrasound waves at the incoming frequencies. Demodulation electronics detect the ultrasound signal. The method aims at quantitative measurements of absorbing tissue or environmental molecules.
