摘要: Abstract HaiMing Wang [Wang HaiMing, Long range optical triangulation utilising collimated probe beam. Optics and Lasers in Engineering, 23(11), 1995, 41–52] studied the influences of size object spot on image laser measuring. This paper points out that study method is inappropriate from two view. The relative power density distribution can be calculated either when assuming an ideal point, which emits a uniform spherical wave over object, or surface light scattering surface. Both conditions show much bigger than Wang’s.
