Length measurement

Industrial optical length measurement delivers swift and reliable measurement results with ultra-high precision over short and long distances. Various measuring principles are available for length measurement using light, such as the triangulation method, the phase measurement process, or the time-of-flight propagation of a pulse. Each measuring principle has advantages and disadvantages and is suitable for specific applications.

Our sensor solutions for length measurement

First Sensor develops and manufactures detector solutions for optical distance measuring devices such as triangulation measurement systems, laser rangefinders, laser scanners, and LIDAR systems. Our one-dimensional, position-sensitive diodes (PSD) are suitable optical detectors for triangulation measurement systems. For laser rangefinders, we offer highly sensitive avalanche photodiodes (APD) for various wavelengths ranging from blue (400 nm) to infrared (1064 nm). Laser scanners and LIDAR systems for distance measurement achieve very high spatial resolutions. For these applications, we supply APD arrays, which are composed of multiple sensor elements with large dynamic ranges as well as wide bandwidths. We also optimize our photodiodes for their special requirements, for example, with reference to sensitivity, amplification, rise time, or capacity.
