© Optics & Photonics International Congress 2019. A measurement method for the cylindrical openings profile of translucent objects is introduced. The optical probe consists of a semiconductor laser, a right circular conical mirror, and a camera embedded with a wide-field lens and a polarizer. The inner profile of an object made of resin was measured. The solution of problems occurring during measurement was discussed and practically verified.
