The skin friction measurement technique based on fluorescent oil film was developed. A specific fluorescent indicator excited by ultraviolet light was chosen to make the oil film and a 2K×2K CCD camera was used to record the image. A delta wing skin friction measurement experiment was carried out, and high resolution skin friction distribution consistent with the theoretical analysis was acquired
