InsideViewTM is an optical coherence domain reflectometer (OCDR-1000) designed to obtain space-resolved reflection information (~ 25 um) inside a fiber optical component, such as a Photonics Integrated Circuit (PIC), for diagnosing quality or design issues. It is a low cost alternative to OFDR technology, however, with much higher dynamic range ~ 80 dB to avoid the masking of small reflection peaks by the large reflections typically from the input surface of the optical device.
