Fast, Multi-Channel Gradient Search Routines

Enhanced throughput in automated alignment processes

Optimization of an analog figure of merit (FoM), such as optical power transmission or a representation of a calculated measure such as Modulation Transfer Function (MTF), can be executed simultaneously across multiple axes. Any analog figure which can be provided as +5/-5 V voltage is accepted.

The gradient search functionality is built into the firmware of the controller which allows fastest execution and best integration into testing or production processes. The lengthy serial motion sequences formerly required are eliminated, the entire process time is drastically reduced.

The number of parallel optimizations possible in a system depends on factors such as the FoM bandwidth, load, and overall positioning bandwidth. Typical configurations can perform XY & angular optimization processes simultaneously.

System configuration / Installation requirements

Gradient search is available for hexapod mechanics H-811.F2 and H-811.I2 in combination with a C-887 hexapod controller that features a high-resolution analog input.

Optimized fast multi-channel photonics alignment systems available

Full optimization functionality and execution at even better speed is obtained using the F-712 dedicated alignment systems. With an integrated 3-axis piezo system for best dynamics and stability, these systems offer unmatched performance in terms of maximum parallel execution capability, speed and tracking.
