​​​​​​Zoller + Fröhlich


Zoller+Fröhlich GmbH is a renowned SME of phase-shift based high-speed Terrestrial Lidar systems, with over 200 employees, represented in 40 countries with UK and USA subsidiaries. The family owned company started in 1963 with the design and implementation of individual control systems for the automobile and engineering industry. The construction of switch cabinets led to the patent of ferrules with plastic sleeves in order to simplify the wiring of control systems. Z+F holds the position of significant pacesetter for manufacturing devices of crimp contacts and cable assembly. Since 1995, the company has become an innovative developer and manufacturer of sensor systems with personalized CAD software solutions for 3D environment modeling. The first visual laser radar was awarded the Dr.-Rudolf-Eberle-Prize 1998 for “Innovations in Baden- Württemberg“. Since then Zoller+Fröhlich is a technological leader in phase-shift based measuring devices through laser sensors with user-orientated concepts as standalone and individualization. Main series of the product portfolio are focused on compact panoramic sensing devices and profiler devices for mobile platforms, e.g. for measuring rail tracks and tunnels. The operating software is shaped and optimized by the own IT development unit. Z+F is partner in R&D projects with international facilities regarding the development of physical measurement systems for contactless, rapid and accurate environment detection. Procedure developments are for combined scene capturing in industrial applications and human control, or for sensor data modeling and pattern matching for large structures in the production technology sector, and the simulation of movement operations of mobile assist systems in populated industrial environments. The recent developments include external sensor integrations, such as HDR photography and thermal surface information as additional information layers on top of the surveyed geometry, giving widely appreciated results for holistic documentations.
