PHOTODIODE ARRAY, REFERENCE VOLTAGE DETERMINING METHOD, AND RECOMMENDED OPERATION VOLTAGE DETERMINING METHOD |
摘要 |
<p>A reverse bias voltage is applied to a photodiode array provided with a plurality of avalanche photodiodes operated in Geiger mode and with quenching resistors connected in series to the respective avalanche photodiodes. Electric current is measured with change of the reverse bias voltage applied, and the reverse bias voltage at an inflection point in change of electric current measured is determined as a reference voltage. A voltage obtained by adding a predetermined value to the determined reference voltage is determined as a recommended operating voltage.</p> |
