Classification: CPC A  G  H | IPC A  G  H

Claim 7:
8. The optical measurement system of claim 1, wherein the control circuit comprises:
a voltage source;
a first inductor coupled to the voltage source;
a first switching circuit coupled to the first inductor and the light source;
a second inductor coupled to the voltage source; and
a second switching circuit coupled to the second inductor and the light source, wherein:
the first switching circuit and the second switching circuit are configured to selectively couple the voltage source to the light source through the first inductor or the second inductor,
the first inductor is configured to control a charging slew rate of a current applied to the light source that increases to start the emission of the light pulse, and
the second inductor is configured to control a discharging slew rate of the current applied to the light source that decreases to stop the emission of the light pulse.
