Measuring and reporting physical parameters in laser biomodulation research

摘要

Abstract: Complete reporting of the physical parameters and laser exposure conditions in laser biomodulation research is essential to understand interaction mechanisms and permit the replication of the results or the extension of their scientific use. Often the biological parameters and procedures are described in detail and physical parameters pertinent to the exposure dose are inappropriately or ambiguously reported. The paper summarizes the minimal physical parameters that should be reported to describe the exposure dose and their measurement. These include the irradiance, the radiant exposure, the exposure duration, the effective irradiated area (e.g. beam diameter if circular), the intensity profile of the radiation field, wavelength(s) or wavelength band, the number of exposures, the time between exposure and a schematic of the exposure apparatus.!10
