摘要：

Described is a new optical reflectometer based on low-coherence interferometry that employs no moving parts. Depth profiling up to a maximum free-space distance of 300 mum ( 150 mum depth) was achieved with a spatial resolution of 23 mum. In a proof-of-principle application, the thickness of a thin plastic film was determined.
