N2 - The assessment of measurement uncertainty of the scanning laser acoustic microscope (SLAM) has not been thoroughly evaluated experimentally. It is essential that the uncertainty of any measurement be fully understood. Both accuracy and precision were experimentally evaluated for the SLAM by measurements on homogeneous liquids of known ultrasonic properties. Using aqueous solutions of bovine serum albumin, the attenuation coefficient accuracy and precision are ±12 percent and +15 percent, respectively. And from Dow Corning 710, a silicon oil, the speed accuracy and precision are ±2.9 percent and +0.4 percent, respectively. Further, an application of the assessment of precision was conducted using duplicate samples of canine skin and wound tissue. From these evaluations of an heterogeneous tissue, the estimated precision in the measurement of the attenuation coefficient and speed was +16 percent and ±1.7 percent, respectively.
