This defect inspection device for emitting illumination light onto a moving and rotating sample and inspecting for sample defects by scanning the sample in a spiral shape or concentric circle shapes comprises: an illumination and detection unit comprising an emission optical system and a detection optical system; a rotary stage for rotating the sample; a rectilinear stage for rectilinearly moving the rotary stage; and a controller for controlling the illumination and detection unit, rotary stage, and rectilinear stage. On the linear path of the rectilinear stage are a scanning start position where illumination light is emitted onto the sample and scanning is started and a sample delivery position where movement of the sample to the scanning start position starts. When the sample arrives at the scanning start position, the defect inspection device starts emitting the illumination light onto the sample without waiting for the rotation speed of the rotary stage to rise to a specified rotation speed for scanning and raises the rotation speed of the rotary stage to the specified rotation speed while scanning the sample.

a controller that performs a control to execute a first measurement and a second measurement.

A physical object processing system is described that includes a process station, a transport facility, an optical imaging system, an image sensor and data process facilities. The transport facility transports objects along the process station that performs processing steps to the object. The image sensor acquires a digital image from an optical image of the physical objects provided by the optical imaging system. The data process facilities in turn process the digital image to control the process station. The optical imaging system maps the optical image of the at least one physical object onto the image sensor at an at least substantially fixed position during a time-interval for acquiring the digital image.
