Phase Conjugate Sonar
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 [...]

MTI Application Note: How to Achieve <1um Accuracy When Measuring Roller Gap
How to Achieve <1um Accuracy When Measuring Roller Gap Roller Gap Measurement with MTI Digital Accumeasure Capacitive Probes Many roll-to-roll finishing processes typically use a calender, or series of hard pressure rollers, to deliver smooth, high-quality products of plastic, textile, or paper (Fig 1). Ensuring a consistent material thickness, however, depends on the ability to monitor, and maintain, a precise gap between rollers. This application note describes a quick and easy means for roller gap measurement. Problem How to measure the small gap between rollers to keep track of product thickness. Typically, it’s not possible to [...]
GaGe Application Note: Creating a Data Link Signal Integrity Test Platform
Creating a Data Link Signal Integrity Test PlatformThis application note describes how a manufacturer of data links utilizes GaGe Instruments’ PC-basedhigh-speed data acquisition digitizers to perform production-level signal integrity testing. Data Link Device Testing The data link device under test (Figure 1) is characterized by comparing test signals that are input to the link with signals measured at the link output. Differences between these two test signals indicate a degradation by the link during transmission. The input and output test signals require sampling at 1 GS/s (GigaSample per second) with at least 14-bit vertical resolution. Both signals must [...]
