Abstract:
A circuit configured to emit pulsed light includes a voltage generating circuit, a light emitting element, a circuit wiring that connects the voltage generating circuit and the light emitting element, a charge capacitor with its end connected to the circuit wiring, and a switching element configured to be turned on or off to apply voltage to the light emitting element. The inductance component for the circuit wiring is derived based on a relationship of the pattern length, pattern width and pattern thickness of the circuit wiring. In this manner, an inductance value of not greater than 1.4 nH can be set and suitably used for achieving an attenuation of at or below 3 dB in a circuit emitting light at a pulse width of 2 ns or less.

Claim (Index 3):
A circuit configured to emit pulsed light, comprising:\n a voltage generating circuit; a light emitting element; a circuit wiring that connects the voltage generating circuit and the light emitting element, wherein the circuit wiring includes a PCB wiring pattern having a pattern length (L) of 1.9 mm or less, a pattern width (W) of 0.15 mm or more, a pattern thickness (H) of 18 \u03bcm or more, and an inductance component that is set to be not greater than 1.4 nH for reducing an attenuation of pulsed light, emitted from the light emitting element and having a pulse width of 2 ns, to not exceed 3 dB, wherein the inductance component is set as a function of the following relationship:\n 0.0002 L [ln((2\u00d7 L )/( W+H ))+0.2235(( W+H )/ L )+0.5](\u03bcH), where \n L is the pattern length in mm units, \n W is the pattern width in mm units, and \n H is the pattern thickness in mm units; \n a charge capacitor with its end connected to the circuit wiring; and a switching element configured to be turned on or off to apply voltage to the light emitting element.
