    Abstract: The embodiments of the present invention relate to communications technology, and disclose an optical power measurement method, an Optical Line Terminal (OLT), and an Optical Network Unit (ONU). The method includes: generating a Physical Layer Operation Administration Maintenance (PLOAM) message that includes an identifier of at least one ONU to be measured and information about a time bucket that is allocated to the ONU to be measured and is used for sending upstream optical signals; sending the PLOAM message to the multiple ONUs; receiving the upstream optical signals that are sent, in the allocated time bucket, by the ONU to be measured; and detecting the received upstream optical signals, and determining the optical power of the upstream optical signals. The present invention avoid waste of bandwidth caused in the prior art when the DBA is required to allocate bandwidth to the ONU to be measured for the purpose of detecting the optical power.

    Abstract: Computer-implemented methods, computer-readable media, and systems for identifying one or more optical modes of an inspection system as candidates for use in inspection of a layer of a wafer are provided. One method includes determining one or more characteristics of images of the layer of the wafer acquired using the inspection system and different optical modes available on the inspection system. The method also includes identifying a first portion of the different optical modes as not candidates for use in the inspection of the layer of the wafer based on the one or more characteristics of the images. In addition, the method includes generating output by eliminating the first portion of the different optical modes from the different optical modes at which the images were acquired such that the output includes a second portion of the different optical modes indicated as the candidates for use in the inspection.
