Measuring the albedo of limited-extent targets without the aid of known-albedo masks

•Methods to measure the albedo of limited-extent targets are summarized.•A new mask-free method is proposed.•The mask-free method does not need a known-albedo mask(s) for calibration. Albedo is a non-dimensional parameter used to quantify the proportion of solar radiation reflected by a surface. Whi...
