Summary:The invention discloses a non-invasive blood fat detection device and method based on near infrared spectroscopy. The detection device comprises a broadband light source laser, an optical fiber beam splitter, a first focusing lens, a second focusing lens, a first optical fiber probe, a second optical fiber probe, a third focusing lens, a fourth focusing lens, a first near infrared spectrometer, asecond near infrared spectrometer, a lock-in amplifier, a heart rate measuring instrument and a computer. According to the non-invasive blood fat detection device and method based on near infrared spectroscopy, firstly, a relation curve of the relative intensity of blood fat characteristic peaks of a near infrared transmission spectrum and the blood fat content is obtained through fitting of a large amount of data of the relative value of the blood fat characteristic peaks at 2222nm positions in the human body pure blood near infrared transmission spectrum to hemoglobin characteristic peaks at2298nm positions and the
