Imaging system and imaging device

An imaging system comprising:

• a light source that irradiates light in a first direction and irradiates light toward a flow channel through which an object to be observed flows in a second direction orthogonal to the first direction;
• an imaging sensor that has an imaging surface orthogonal to the first direction and on which a plurality of pixels are two-dimensionally arranged in a manner non-parallel to the second direction and that images light passing through the flow channel to output an interference fringe image;
• and
• a processor configured to generate a super-resolution interference fringe image based on a plurality of interference fringe images output from the imaging sensor,
• wherein one direction of an arrangement direction of the two-dimensional arrangement is an X direction and the other direction is a Y direction in the imaging surface, and the plurality of pixels are arranged in the X direction at a first arrangement pitch and arranged in the Y direction orthogonal to the X direction at a second arrangement pitch that differs from the first arrangement pitch.
