exemplary embodiments of arrangements and methods providing information associated with a sample are described . for example , using such exemplary arrangements and methods , it is possible to receive an unpartitioned electro - magnetic radiation from the sample . further , first data associated with first luminescent characteristics of at least one first molecule of the sample and second data associated with second luminescent characteristics of at least one second molecule of the sample can be obtained based on the unpartitioned electro - magnetic radiation . at least two of the photo - luminescent properties of the sample may be measured simultaneously as a function of the first and second data . further , the information regarding the molecules of the sample may be determined as a function of the photo - luminescent properties .
