All-optical thermometry presents a promising avenue of investigation for sensitive biological and electronic systems, with methods free of radio-frequency interference of particular importance. In this work, an all-optical scanning fiber thermometer is tested and shown to possess 5μm spatial and 20mK/√Hz temperature resolution. This probe is then used to generate noncontact scanning thermal images of active circuit elements with microscale thermal features.
