General-purpose colour cathode ray tube (CRT) monitors are used commonly for image display in personal computer-based picture archiving and communication system (PACS) and telemedicine systems. At present, however, we have not enough information about their performance or reliability for this task. Therefore, we studied the performance of five(More)
A dual beam laser diode scanning method for an ultrahigh speed laser printer is proposed and its feasibility is tested. Two separate laser beams are scanned simultaneously by one facet of a polygon mirror. By employing this method, power emitted from each laser and the rotation speed of the polygon mirror can be reduced to half, compared with those in(More)
