System and method for controlling a light source for cavity ring-down spectroscopy |
摘要 |
An apparatus and method for controlling a light source used in Cavity Ring-Down Spectroscopy. The apparatus comprises a controller that generates a control signal to activate and deactivate the light source based on a comparison of an energy signal from a resonant cavity and a threshold. The light source is activated for a predetermined period based on the stabilization time of the light source and the time necessary to provide sufficient energy to the resonant cavity. Thereafter the controller deactivates the light source for a predetermined time period by interrupting its current source so that the light energy in the cavity ring downs and so that the presence of analyte can be measured. The light energy from the light source is directly coupled to the resonant cavity from the light source.
