Title (EN) PHOTODETECTOR
(FR) PHOTODÉTECTEUR
(JA) 光検出器
Abstract:
(EN) A photodetector provided with: a light reception unit (2) provided with a SPAD (4) configured to respond to entry of photons, the light reception unit (2) being configured to output a pulse signal when the SPAD responds; and a pulse rate control circuit (20) configured to control the sensitivity of the light reception unit so that the pulse rate, which is the number of times a pulse signal is outputted from the light reception unit per unit time, is equal to a set value set in advance, is within a set range including the set value, is equal to or greater than the set value, or is equal to or less than the set value.
(FR) Un photodétecteur comprend : une unité de réception de lumière (2) pourvue d'une SPAD (4) conçue pour répondre à l'entrée de photons, l'unité de réception de lumière (2) étant conçue pour émettre un signal d'impulsion lorsque la SPAD répond ; et un circuit de commande de taux d'impulsions (20) conçu pour commander la sensibilité de l'unité de réception de lumière de telle sorte que le taux d'impulsions, qui est le nombre de fois où un signal d'impulsion est émis par l'unité de réception de lumière par unité de temps, est égal à une valeur de consigne définie à l'avance, se trouve à l'intérieur d'une plage définie comprenant la valeur de consigne, est supérieur ou égal à la valeur de consigne, ou est inférieur ou égal à la valeur de consigne.
(JA) 光検出器は、フォトンの入射に応答するよう構成されたSPAD(4)を備え、SPADが応答するとパルス信号を出力するよう構成された受光部(2)と、受光部からのパルス信号の単位時間当たりの出力数であるパルスレートが、予め設定された設定値、該設定値を含む設定範囲内、該設定値以上、又は、該設定値以下となるように、受光部の感度を制御するよう構成されたパルスレート制御回路(20)と、を備える。
