How to synchronise detector (ccd) with mechanical chopper to measure absorbance change (and hence spectra) in Transient absorption spectroscopy ?

1. How to detect change in absorbance (delta A) spectra in transient absorption spectroscopy using CCD, mechanical chopper? 2. How to measure I(unpumped) and I(pumped) both at different...
