Abstract

The present disclosure provides a thickness measuring method and device. The thickness measuring method is used for measuring a thickness of a layer to be measured of a light-transmitting sample to be measured and comprising the steps of: placing the sample to be measured between an optical device and a metal layer, the optical device comprising a light incident surface and a light exit surface; adjusting incident light emitted to the light incident surface of the optical device so that an intensity of light exiting the light exit surface of the optical device is less than 10W/m, so as to obtain optical parameters of the incident light; and calculating a thickness of the layer to be measured according to the optical parameters of the incident light.
