Optical power meter
摘要:
An optical power meter is used to measure the optical power of optical energy passing along an optical fibre (11). The power meter includes means (12,13) for tapping optical radiation from the optical fibre (11), a transducer (1) for converting the tapped optical radiation into an electrical signal, and means (5,6) for displaying the amplified signal.
