ABSTRACT:
A non-zero feedback radiant flux reduces a radiant flux sensor's primary response excursion by keeping the total radiant flux on the sensor virtually constant. An increase in signal radiant flux is countered by a virtually equal decrease in feedback radiant flux. Reduced primary response excursion suppresses the effects of energy storage mechanisms within the sensor. Smaller response excursions decrease the sensor's response time and nonlinearity. Since many radiant flux feedback sources are virtually noiseless, radiant flux feedback does not degrade the sensor's Noise Figure.
