Double-light-source glass stress detection device

The utility model provides a double-light-source glass stress detection device, which relates to the stress detection technology in the glass production process, and comprises an emission head (101) and a detection measuring head (102) which are correspondingly arranged on the upper side and the lower side of glass to be detected, and further comprises a reference measuring head (103), a detection light source (01) is arranged in the emission head (101), and the detection light source (01) is arranged in the reference measuring head (103). Light emitted by the detection light source can penetrate through the glass to enter the detection measuring head, a reference light source (01 ') identical to the detection light source (01) is installed in the reference measuring head (103), and light emitted by the reference light source is transmitted in the reference measuring head (103). According to the device, the glass stress is measured by a transmission method, the glass stress detection is realized through the p
