Abstract
GEC Ferranti have been manufacturing rotating instruments such as inertial quality gyroscopes and rotating polygon scanners for many years. Markets for scanning devices vary widely and include cameras, thermal imaging, laser printing and projection. The advent of high resolution laser video projection brought about new challenges in scanning technology. Initially, these challenges could only be met with complex and expensive devices and ancillary equipment. Based on our experience and success in the markets already mentioned, we have developed a range of compact line scanning devices which can be manufactured on a production basis, and which meet the requirements of scan rate, accuracy and reliability demanded by HDTV systems.
