Table 1.

Comparison of the position differences of the aligned lasers on both side walls between the proposed and conventional methods.

		Conventional Method (mm)
	Proposed Method (mm)	High‐accuracy level ^b	Low‐accuracy level
b‐a ^a (Fig. 4(b))	1.4	2.1	26.0

^{^a}

The value is an SD of four measurements.

^{^b}

A high‐accuracy level with the resolution of 0.44 mm/1,000 mm was used.
