Title:
WEAK LIGHT DETECTOR HAVING CHARGE RESETTING MEANS
Document Type and Number:
Japanese Patent JP3760240
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a weak light detector that has a charge resetting means for releasing a charge accumulated in a circuit without increasing an input capacity and can measure the number of photons.
SOLUTION: In the weak light detector including a substrate having an integration type reading circuit including a photo detecting means and a field effect transistor (FET), and a charge resetting means for releasing charges accumulated in the integration type reading circuit, the photo detection means is either a PIN photodiode or an avalanche photodiode (APD), the charge resetting means has a rotary mechanism, a probe that is rotated as the rotary mechanism is rotated, and a connection section for connecting the probe to the outside.
