Abstract
A combined detector capable of simultaneously detecting both a value indicating a physical/chemical phenomenon such as a pH value and the intensity of an energy beam such as light. The combined detector comprises a physical/chemical phenomenon detecting system (10) and an energy beam detecting system. The physical/chemical phenomenon detecting system (10) has a sensing section (21) whose potential varies with a physical/chemical phenomenon, a charge supply section (22) for supplying first charge to the sensing section, a charge supply control section (23) provided between the sensing section (21) and the charge supply section (22), a first charge storage section (26) for storing the first charge transferred from the sensing section (21), and a charge transfer control section (27) provided between the sensing section (21) and the first charge storage section (26). The sensing section (21) includes a semiconductor charge generating portion (15) for generating the first charge and second charge when receiving an energy beam such as light. The energy beam detecting system has the semiconductor charge generating portion (15) and a second charge storage section (31) adapted to store the …
