  • Method and aid for the early recognition of sunburn
    Patent number: 6488622
    Abstract: A method for the early detection of sunburn is provided in which the reflection spectrum of the irradiated skin is considered. A color change made perceptible to the human eye is obtained from the specific absorption and reflection behavior. The change is made to occur when a predetermined borderline spectrum is reached. A device is also provided that changes the reflection spectrum of the irradiated skin, which is determined by the specific absorption and reflection behavior, such that the changed reflection spectrum brings about a color change perceptible to the eye when a predetermined borderline spectrum is reached, whereas no color change perceptible to the eye is yet noticeable if the reflection spectrum is unchanged.
