Spiroid wave analysis was a type of reading generated by the science station on the USS Enterprise.

In 2269, Spock estimated that a full spiroid wave analysis of the spiroid epsilon wave causing the crew's shrinkage would take eight years. James T. Kirk told him to bypass the analysis, as they only had twenty nine minutes before they became too small to operate the starship's controls. (TAS: "The Terratin Incident")
