OPTICAL DEVICE AND SYSTEM

Title:

OPTICAL DEVICE AND SYSTEM

Document Type and Number:

Japanese Patent JP2018006989

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To improve accuracy of information based on electrons generated in a photoelectric conversion unit and holes generated in a photoelectric conversion unit.SOLUTION: A signal correlated to a difference between a first detection node's electric potential based on electrons generated in a first photoelectric conversion unit in a first period and collected by a first collection node and holes generated in a second photoelectric conversion unit in a second period differing from the first period and collected by a second collection node and a second detection node's electric potential based on holes generated in the second photoelectric conversion unit in the first period and collected by a fourth collection node and electrons generated in the first photoelectric conversion unit in the second period and collected by a third collection node is generated.SELECTED DRAWING: Figure 3
