and the calculated decay Ndtid- These functions are in t ms of discrete times (/ ) because the counted photons are collected into channels, each with a known time (tk) and width (AO  

The instrument response function, sometimes called the lamp function, is the resp( ise of the instrument to a zero-lifetime san le. This curve is typically collected using a tUlute scattering solution such as colloidal silica (Ludox) and no emission filtor. This decay represents the shortest time jnrofile which can be measured by the instrument. The lamp function in Hgure 4.8 is quite narrow. 

Mathnnaticaily, the concept of convolution can be expressed as follows. Each 5-funcdon excitadon is assumed to excite an impulse response at tt,
