Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...
Coherent combining of fiber amplifiers is a promising technique to increase the overall output power from efficient and compact laser sources while simultaneously maintaining beam quality. Active phase controlling of master oscillator power amplifiers (MOPA) is one of the most common coherent beam combining (CBC) architecture [1-3]. Up to now, the highest-power obtained by CBC and CBC of larges...
