Abstract
We study a simple setup for non-destructive detection of photon number. We in particular compare the device's inaccuracy and its phase disturbance to the uncertainty principle. As the traditional uncertainty principle involves neither inaccuracy nor disturbance, a new type of uncertainty relation is employed. Self-phase modulation is taken into account, losses are neglected.
