Latest Patents

One of Fedchak's latest patents is an "Optomechanical pressure measurement system and method using the vibrational modes of a membrane." This system measures pressure in the range of 10Pa-10Pa by analyzing the vibrational properties of an ultra-thin membrane. By independently measuring the thickness and density of the membrane, along with the vibrational mode properties, the system can function as a primary pressure sensor. The membrane is mounted on a vibration-isolated mount and excited by a drive force. A laser beam interacts with the membrane, and an optical phase detector captures the oscillation amplitude and parameters affected by the membrane's vibration. The system can compute mechanical damping and pressure based on the membrane's vibration characteristics.

Another significant patent is the "Uniaxial counter-propagating monolaser atom trap." This invention cools and traps atoms using a single laser beam. It includes an atom slower that decelerates atoms to form slowed atoms, along with an optical diffractor that utilizes multiple diffraction gratings to produce reflected light. The trapping region combines the reflected lights to create trap light, which interacts with the slowed atoms to produce trapped atoms.
