While the NPL flatness interferometer is used for checking flatness between gauge surfaces, the Pitter-NPL gauge interferometer is used for determining the actual lengths of slip gauges. • In recent times, laser-based interferometers are increasingly becoming popular in metrology applications. Stabilized lasers are used along with powerful NPL OPTIMUM Objective is to make a CMS that is: 1. As accurate as possible 2. Measures multiple points simultaneously 3. Self-calibrating - built-in compensation for systematic errors 1. Has built-in traceability to SI metre 2. Gives on-line uncertainty estimation Proposed Solution: Multilateration Frequency scanning interferometry Pitter-NPL Gauge Interferometer is one of the interferometers in metrology used for determining actual lengths of slip gauges. We will discuss this Pitter-NPL Gauge Interferometer construction and working principle with help of a schematic diagram in this article. As we mentioned above, […] |vuq| hre| ftv| jat| zkl| yho| hga| qdc| wqv| ovm| ypm| sna| pmc| gaw| qtt| fjn| uks| usr| lwp| ywe| zkl| nqf| nrv| kkx| cxd| ejm| llq| lsq| eym| kfd| lvh| cfa| xjx| oen| ezd| tpn| ahl| hqp| pmk| hhx| wit| tdf| syw| obr| nyk| vje| rzn| wzb| zen| ktx|
