Latest Patents

Elena holds a patent for a system titled "Non-contact photoacoustic spectrophotometry insensitive to light scattering." This innovative system is designed to measure the absorption spectrum of materials without direct contact. It utilizes a modulated light source, such as a tunable pulsed laser, to generate photoacoustic signals. The system features a non-contact detector that monitors the surface of the container holding the material. This detector includes a second light source, focused on the container's surface, which transmits reflected light to an interferometer. The interferometer produces an interference signal proportional to the acoustic pressure, allowing for the calculation of the absorption coefficient. By employing multiple wavelengths from the tunable pulsed laser, an absorption spectrum can be generated.
