differential gain การใช้

The gray bands emerging from the center off to the lower right and upper left were for differential gain, contrast, and white level.
Within the chart the tools necessary to adjust perspective, framing, linearity, frequency response, differential gain, contrast and white level ( brightness ) are all provided.
So the phase differences between two consecutive lines ( so-called differential phase ) are converted to differential gain distortions . ( Hue is preserved at the risk of decreased saturation ).
Where ? r0 is the intrinsic carrier radiative lifetime of the bulk material, a is the differential gain, v g is the group velocity, ? p = Q / ? L is the photon lifetime, ? L is the lasing frequency, ? is the spontaneous emission coupling factor which is enhanced by the Purcell effect, and 1 / ? total = F / ? r0 + 1 / ? nr where ? nr is the non-radiative lifetime.
