Abstract :	[en] Non-contact optical measurement methods are essential tools in many industrial domain. Hololab developed an original out of plane, in line and almost common path interferometer based on polarization states separation using a coated prism for fringes projection. This setup has proven efficient in the field of arts and archaeology but does not meet the demands of the industrial world. Above the acquisition speed and the post treatment process, one of the disadvantages comes from the sensitivity of the system to the environment. To overcome this disadvantage, the coated prism is substituted by a Savart plate. This device has already been used in another field of optical metrology as a shearing device. Many advantages of the prism substitution are discussed and recorded fringes patterns will be shown.
