Abstract
A time-of-flight measuring device for performing a hardware-based high-speed data compression process before transferring the data from a signal recorder to a data processor is provided. A time-series digital signal recorded by a signal recorder is converted to a plurality of time-series digital signals by being divided into a bit string including baseline information and a bit string not including the baseline information. Then, the time-series digital signal consisting of a bit string not including the baseline information is compressed by run-length encoding, such as zero length encoding or switched run-length encoding. Subsequently, static Huffman coding is performed on each of the time-series digital signals to reduce the data amount.
