The fiber optic fluorescence lifetime (SeePhase™) family systems, based on its proprietary frequency domain “phase-locked” detection technology, allows the remote, real-time identification and measurement of chemical and biological fluorescent markers in the field.
Its compact package, low power operation, state-of-the art data processing and communications architecture and affordable price makes it a very attractive solution for a large number of applications. SeePhase™ system is based on measuring the laser induced fluorescence lifetime of target fluorophores in response to a spatially and temporally modulated laser light excitation signal at eye safe energy levels.
The fluorescence lifetime of the target fluorophores is measured using the principle of “frequency- domain” or “phase-locked” detection.
