Optical Sensors Displace Legacy Inertial Measurement Technology
Rail authorities continue specifying optical and laser sensor technology over legacy inertial systems as optical sensors deliver greater measurement precision and repeatability across high-speed operating conditions that degrade inertial system accuracy faster, with suppliers such as Plasser and Theurer expanding optical production capacity to meet this technology transition across major high-speed rail networks worldwide. Optical and Laser Measurement Systems grow about 11.9% a year, and gross margins run 30% to 48%. The trend needs continued engineering investment and rewards suppliers with proven precision data. Buyers also review trial and precision documentation before every seasonal contract renewal.
Market Impact: buildout adds 6-9% yearly installation demand
