Microcomputerized ultrahigh-speed transient digitizer and luminescence lifetime instrument

A high-speed transient digitizer and a versatile luminescence lifetime insrument are described. A Z-80-based microcomputer permits rapid acquisition of transients, signal averaging, baseline subtraction, single or double exponential decay fitting, deconvolution, and graphics display of the transient and its semilogarithmic plot of decays on an oscillo-scope or an X-Y plotter. Data can also be transferred to more powerful computers for further data reduction or higher quality plots. Applications that exploit the speed and convenience of the system are described.
