Patent ID: 7846191

Claim:
A system to provide non-coherent pulsed light, the system comprising: a lamp to produce non-coherent pulsed light; a current supply to controllably provide current to said lamp and to enable controlled spectral distribution and controlled temporal intensity distribution of said non-coherent pulsed light within a pulse of said non-coherent light, the controlled spectral distribution and the controlled temporal intensity distribution of said non-coherent pulsed light being controlled, at least in part, by altering the current from the current supply to cause altering the spectral distribution and the temporal intensity distribution during the pulse; one or more changeable filters to enable separate controlled altering of the spectral distribution and the temporal intensity distribution of said non-coherent pulsed light during the pulse; a feedback mechanism configured to: perform a determination if output resulting from application of said pulse of non-coherent light on a target area is in accordance with a treatment plan, and change the treatment plan to perform, based, at least in part, on the determination of the feedback mechanism, one or more of: altering the current from the current supply to alter the spectral distribution and the temporal intensity distribution of said non-coherent pulse light during the pulse, and controlling the one or more changeable filters; and a controller unit to control at least one of the current supply, the one or more changeable filters and the feedback mechanism, the controller unit configured to enable control one or more of the spectral and the temporal intensity distribution of said non-coherent pulsed light for the selected treatment, based, at least in part, on data received from said feedback mechanism.
