With the development of science, the precision of surveying instrument and itS degreof tomatianion is getting higheL Therefore conventionaI means of teSting can't meet thneed for today A new system consisting of Double Frequency Laser Intefferometer anIrelevant sensor equipment has been designed. This system can be used for verification athe length standard, realizing automation and making test procedure more accuthe.This paPer discusses the indoor verification for EDMI, leveling staff and digital IeveI byusing Double Frequency Laser Interferometer Measurement System.
