Modern X-ray imaging systems require low noise high-count-rate multichannel front-end electronics. Such systems widely use charge-sensitive amplifiers (CSA) with pole-zero cancellation (PZC) circuits ...

We demonstrate two adaptive methods to equalize mode-dependent gain (MDG) in multi-mode erbium-doped fiber amplifiers (MM-EDFAs). The first method uses a spatial light modulator (SLM) in line with the ...
