title: Interference problems in a coherent aberration sensor.
abstract: Fast IR wave-front aberration sensors are essential to the improved performance of HEL systems. However, one must not transfer sensor designs which function well (in principle and in practice) for the incoherent blackbody realm over into the coherent environment without first considering possible interference problems. A case history of one such sensor which failed this precept is considered.
