Abstract
An imaging and asynchronous laser pulse detector (ALPD) device, imaging cell of the imaging and ALPD device and method of use is disclosed. A detector generates an electrical signal in response to receiving an optical signal, wherein a frequency of the electrical signal is indicative of a frequency of the optical signal. A first detection/readout circuit is sensitive to a first frequency range, and a second detection/readout circuit is sensitive to a second frequency range. The first detection/readout circuit allows the electrical signal to pass from the first detection/readout circuit to the second detection/readout circuit.
