輪胎激光無損檢測儀

Tyre laser speckle non-destructive testing instrument

• 輪胎激光散斑無損檢測儀是基于激光剪切散斑干涉效應(yīng)，利用輪胎在受激光照射后產(chǎn)生的干涉散斑場的相關(guān)條紋來檢測光束波前的相位變化。尤其應(yīng)用在輪胎生產(chǎn)線的檢測或線下的鼓包檢測，儀器采用**的相移技術(shù)，測量輪胎表面的形變位移導(dǎo)數(shù)，檢測結(jié)果不受輪胎剛體運動的影響。
• 通過檢測儀的激光擴束以扇射角度照射輪胎，通過加壓加載后，獲取散斑條紋圖像進行比對，來判斷輪胎鼓包現(xiàn)象。
• Tyre laser speckle non-destructive testing instrument, basing on laser shearing speckle interferometry, is used to inspect the phase change in front of the beam wave and relevant strips of interferometric speckle field after laser irradiation.In particular to the inspection of tyre product line or offline swelling inspection, the instrument adopts precise phase shift technique for measuring the deformation displacement derivative of the tyre surface, and the inspection result is not affected by the rigid motion of tyre.
• The laser beam expander of the testing instrument irradiates the tyre at a fan angle, after pressurizing and loading, the image of the speckle stripe is acquired for comparing, so as to judge the swelling of tyre.
