Summary:The invention discloses a non-contact water temperature measuring device based on an optical frequency comb. A temperature sensing module is composed of a femtosecond laser, a first spectroscope, a second spectroscope, a second reflector, a glass water tank, a first reflector, a third reflector, a double-sided reflector, an electric displacement table, a fourth reflector, a first photoelectric detector and an oscilloscope. A positioning module is composed of a continuous wave solid laser, a third spectroscope, a fifth reflector, a double-sided reflector, an electric displacement table, a second photoelectric detector and an oscilloscope. The first photoelectric detector and the second photoelectric detector complete detection; the oscilloscope is used for data storage and phenomenon observation; the oscilloscope transmits data to a computer in real time, and the computer processes the data in real time; and when the temperature in water changes, the water refractive index changes. Theoptical path is equal to
