Nuclear Reactor Cooling Liquid Flow Measurements Customer Case The customer needs to make a flow meter that is able to measure the flow of liquid through a tube. In this case, water is used for nuclear reactor cooling. The obstacle is that the liquid must be measured while the tube remains intact. GaGe Case Solution Since the customer knows the application, he already has his own signal generator that produces the ultrasound, so he only required a good data acquisition card in order to acquire these ultrasonic signals. An amplified version of the signal coming from the transducer goes [...]

Phase Conjugate Sonar Customer Case Dissipationless physical systems, such as simple planetary motion or a swinging pendulum, exhibit time-reversal invariance. This means that if time were reversed the way a film projector can be, then the resulting motion would be allowed by the equations governing the system. It follows that if all velocities in a dissipationless system are suddenly reversed, the system will follow a time-reversed trajectory. Dissipationless or adiabatic wave propagation is time-reversal invariant. Phase Conjugate Optics involves the deliberate reversal of complex light paths. A customer is doing Phase Conjugate Sonar using sound instead of light. The [...]
