Abstract: This invention is an apparatus for imaging metrology, which in particular embodiments may be integrated with a processor station such that a metrology station is apart from but coupled to a process station. The metrology station is provided with a first imaging camera with a first field of view containing the measurement region. Alternate embodiments include a second imaging camera with a second field of view. Preferred embodiments comprise a broadband ultraviolet light source, although other embodiments may have a visible or near infrared light source of broad or narrow optical bandwidth. Embodiments including a broad bandwidth source typically include a spectrograph, or an imaging spectrograph. Particular embodiments may include curved, reflective optics or a measurement region wetted by a liquid. In a typical embodiment, the metrology station and the measurement region are configured to have 4 degrees of freedom of movement relative to each other.
Abstract translation: 本发明是一种用于成像测量的装置,其在特定实施例中可以与处理器站集成,使得计量站离开处理站而不是耦合到处理站。 计量站设置有具有包含测量区域的第一视野的第一成像照相机。 替代实施例包括具有第二视野的第二成像相机。 优选实施例包括宽带紫外光源,但是其他实施例可以具有宽或窄光带宽的可见光或近红外光源。 包括宽带宽源的实施例通常包括光谱仪或成像光谱仪。 具体实施例可以包括弯曲的,反射光学的或由液体润湿的测量区域。 在典型的实施例中,计量站和测量区域被配置为具有相对于彼此的4个移动自由度。
