    • PROBLEM TO BE SOLVED: To allow easy measurement of the resolving power of an image sensor for exposure position adjustment of an exposure device.SOLUTION: Light is transmitted through a mask for calibration including a mask part including an image capture window for image capture, a glass surface part provided below the mask part and constituted of a glass material bonded to the vicinity of the image capture window with an adhesive, a shielding line group of shielding lines provided on the image capture window and the glass surface part and constituted of a shielding material. Light transmitted through parts other than the shielding line group is received, and the received light is converted to image information from the top of the received light, and resolving power information is measured on the basis of the image information.
    • 要解决的问题:为了容易地测量用于曝光装置的曝光位置调整的图像传感器的分辨率。解决方案:光通过用于校准的掩模传输,包括包括用于图像捕获的图像捕获窗口的掩模部分, 玻璃表面部分设置在掩模部分下方并且由粘合剂粘合到图像捕获窗口附近的玻璃材料构成,屏蔽线组设置在图像捕获窗口和玻璃表面部分上,并由屏蔽层 材料。 接收通过除了屏蔽线组以外的部分的光,接收到的光从接收光的顶部转换为图像信息,并且基于图像信息测量分辨率信息。

    • PROBLEM TO BE SOLVED: To provide an exposure device able to improve, for example, alignment accuracy, according to an embodiment.SOLUTION: According to an embodiment, an exposure device having an acquiring section and a measuring section are provided. The acquiring section acquires a plurality of measurement values. The measurement values are the measurements of different amounts of focus offset. The measurement values indicate a displacement distribution within a shot area. The measuring section obtains a plurality of distortion errors from the measurement values. According to the amounts of focus offset and the distortion errors, the measuring section obtains the correlation between the amounts of focus offset and alignment correction values. The alignment correction values are values for correcting distortion errors.
    • 要解决的问题:根据实施例,提供能够改善例如对准精度的曝光装置。解决方案:根据一个实施例,提供一种具有获取部分和测量部分的曝光装置。 获取部获取多个测量值。 测量值是不同焦距偏移量的测量值。 测量值表示拍摄区域内的位移分布。 测量部分从测量值获得多个失真误差。 根据聚焦偏移量和失真误差,测量部分获得聚焦偏移量和对准校正值之间的相关性。 对准校正值是校正失真误差的值。
