ABSTRACT:
A system and method for determining the local distribution of measurement variables being measured relative to or present in a predefined measurement area of a biological sample wherein in a first optical measuring process the local distribution of a first of the measurement variables is determined using a sensor film applied to the measurement area and including a luminescence indicator reacting to the first measurement variable by a change of luminescence decay time. The luminescence decay time or a quantity derived therefrom is recorded by an imaging technique as a function of the first measurement variable. In a second optical measuring process the local distribution of a second of the measurement variables is determined simultaneously or immediately following, using an imaging technique which is effective through the sensor film of the first optical measuring process.
