| Summary: | A new method for pulsed radiation measurements is studied by an application of the information theory of discrete systems. It is derived from entropy concept that in order to measure the photon density with the maximum conversion rate of a counter subjected to pulsed photon beams, the density λ of a Poisson source must satisfy the relation of λ
b
=ln
2 when the resolving time τ of the counter lies between the pulse width
b
and the period (1/
f
).
Actual devices using feedback circuits for satisfying the above condition are proposed. |
