Abstract: This paper will review optical reflectometry techniques that are capable of achieving spatial resolutions of less than 1 cm. Advantages and disadvantages of these techniques will be discussed. A white light interfometry technique known as optical low-coherence reflectometry will be emphasized. This technique has been used to obtain spatial resolutions on the order of tens of microns and reflection sensitivities as low as -148 dB.
