A method of detecting foreign objects in display manufacturing process, wherein the method comprising steps as flows: First a laser source and a laser detector are provided on a first side of a target to be measured, wherein the laser detector is supported by an adjustable gauge to provide the laser detector both horizontal and vertical movement. Then, a reflector located is provided on a second side of the target, wherein a laser beam coming from the laser source passes through a detecting position over the surface of the target, and is reflected to the laser detector by the reflector. Subsequently the intensity of the reflected laser beam is received and measured of by the laser detector.
