Patent number: 6882433Abstract: An expanding measuring beam is inserted into a cavity of a frequency-scanning interferometer. The expanding measuring beam encounters non-specular (diffuse) reference and object surfaces so that the reflected light can be imaged with an imaging system of reduced dimension. The compact interferometer is adaptable to a variety of applications. For example, the compact interferometer can be incorporated into a sensor of a multi-stage measuring instrument or into a handheld imager.Type: GrantFiled: June 30, 2003Date of Patent: April 19, 2005Assignee: Lightgage, Inc.Inventors: Joseph C.
