    摘要: An alignment method of micro-alignment members includes a first step for moving a reticle, which is movably disposed between a first position and a second position, to face a first microscope in the first position, and for aligning a center of the reticle with an optical axis of the first microscope while observing the reticle by the first microscope, a second step for moving the reticle to the second position to face a second microscope in the second position, and for aligning the center of the reticle with an optical axis of the second microscope while observing the reticle by the second microscope, a third step for disposing a first micro-alignment member such that a center of the first micro-alignment member aligns with the optical axis of the second microscope, and a fourth step for disposing a second micro-alignment member instead of the reticle to face the first micro-alignment member.

    摘要: A distance measuring device measures a distance from a phase difference of beaten down processing signals even when fluctuations occur in a frequency of an oscillator. The distance measuring device includes a laser unit, a dividing device, a reference light receiving unit, and a measuring light receiving unit. The distance measuring device further includes an oscillator, a first mixer, a second mixer, a fourth filter, a fifth filter, a third mixer, a sixth filter, a second filter, a phase difference measuring unit, and a distance measuring unit. The phase difference measuring unit measures a phase difference of the two beat signals extracted by the sixth filter and the second filter. The distance measuring unit measures a distance based on the phase difference measured by the phase difference measuring unit.
