The CHARA array at Mt Wilson, California, is the worldтАЩs highest angular resolution instrument, able to image the surface of stars and measure angular diameters down to about 200 micro-arcseconds. With six simultaneous telescopes, ~300 optical elements, dozens of active servo loops and ~500 actuators, the system is already arguably the most complex optical or infrared telescope system in the world. ...

... DLTS . ... Deep Level Transient Spectroscopy ( DLTS ) is a unique and powerful tool for the study of electrically active defects (known as traps) in semiconductors.
