Abstract: Methods and apparatus for imaging light are disclosed. Light is imaged by collecting light, converting the collected light into a electrical charge signal, multiplying the electrical charge signal to produce multiple electrical charge signals with associated levels of gain, converting the electrical charge signals to voltage signals, and developing an output signal from one or more of the voltage signals that represents the collected light. The electrical charge signal may be multiplied using an electron multiplication device associated with multiple taps to produce the electrical charge signal with different levels of gain.
