SYSTEMS AND METHODS FOR PERFORMING RAPID FLUORESCENCE LIFETIME, EXCITATION AND EMISSION SPECTRAL MEASUREMENTS

摘要

Exemplary systems and methods for obtaining information associated with at least one portion of a sample can be provided. For example, a first radiation can be received and at least one second radiation and at least one third radiation can be provided as a function of the first radiation. Respective intensities of the second and third radiations can be modulated, whereas the second and third radiations may have different modulation frequencies, and the modulated second and third radiations can be directed toward the portion. The photoluminescence radiation can be received from the portion based on the modulated second and third radiations to generate a resultant signal. The signal can be processed to obtain the information which is/are photoluminescence lifetime characteristics and/or a polarization anisotropy of the portion. According to another exemplary embodiment, the photoluminescence radiation can be received and the photoluminescence radiation may be based on wavelengths thereof.
