The view through a bamboo screen. From moire patterns to blackholes

摘要

X-ray astronomical imaging methods are discussed that use Moirefringes. The author describes his experiences in designing and operatingX-ray astronomical detectors. His first experiment was an instrumentflown onboard NASA's X-=15 rocket and used a rotating metal grid todistinguish between point and diffuse sources. Work on the preciselocation of various astronomical X-ray sources such as Sco X-1 is alsodescribed. The author also describes his work with a modulationcollimator on Cyg X-1. Work involved in studying the Crab nebula andsolar flares is also described
