response time, τR of a detector

The time required for the detector output to go from the initial value to a percentage (e.g. 99%) of the final value. In the case of an exponential behaviour of the detector $τ R$ can be related to the time constant $τ c$ . The rise time $τ r$ is the time required for the detector output to vary between given percentages (e.g. from 10% to 90%) of the final value. Similarly, the fall time $τ f$ is the time required for the detector output to vary between given percentages (e.g. from 90% to 10%) of the initial value.
