Use and Future Development of Optical Measurement Technology in the Study of Wood Surface Roughness CiteSpace-Based Scientometric Analysis (2003 through 2022)

Abstract

Although the contact probe measurement technique is excellent for wood surface roughness measurement, it is necessary to reevaluate the advantages and future development direction of optical measurement techniques in this field, given the emergence of optical measurement techniques such as laser technology and the increasing academic interest in wood surface roughness. The traditional review method, due to its rather limited research directions, only provides a macroscopic and qualitative description of certain laws and conclusions. The purpose of this review is to use the bibliometrics theory and method to comprehensively sort out the research hot spots in this field and explore them in depth. The bibliographic analysis of 233 documents from the Web of Science database was carried out using CiteSpace's bibliographic network analysis, visualization analysis, and other functions. We discuss in detail the advantages of optical measurement techniques in the characterization of wood surface roughness in two- and three-dimensional (2D and 3D) conditions, the research on the separation of structural roughness and machining roughness of wood using optical measurement techniques, and we explore the future direction of the development of optical measurement techniques in the study of wood surface roughness. The results of the study will act as important references for new researchers who want to enter into the field, to obtain an in-depth understanding of the research hot spots, and to acquire valuable scientific information.
