About The Book
In 1984 Desmond O’Connor and David Phillips published their comprehensive book Time-correlated Single Photon Counting. At that time time-correlated s photon counting, or TCSPC, was used primarily to record fluorescence decay functions of dye solutions in cuvettes. From the beginning, TCSPC was an amingly sensitive and accurate technique with excellent time-resolution. However, acquisition times were relatively slow due to the low repetition rate of the light sources and the limited speed of the electronics of the 70s and early 80s. Moreover, TCSPC was intrinsically one-dimensional, i.e. limited to the recording of the form of a periodic light signal. Even with these limitations, it was a wonderful tenique. More than 20 years have elapsed, and electronics and laser techniques have made impressive progress. The number of transistors on a single chip has approximately doubled every 18 months, resulting in a more than 1,000-fold increase in complity and speed. The repetition rate and power of pulsed light sources have increased by about the same factor.
