The NanoTrak® auto-alignment controller combines an intelligent, active-feedback, alignment control system and a two channel, piezoelectric controller into a single bench top unit. As part of the APT™ series, this auto-alignment system represents the latest developments in automated optical alignment technologies. This system is a basic building block from which advanced alignment systems can be quickly configured. It can be fully integrated with our extensive selection of motorized positioning systems, including our 3-Axis NanoMax and 6-Axis Nanomax flexure stages with piezo actuators.

The initial coupling of light from one device (e.g. fiber) to another involves searching a multidimensional space until a signal is detected. The NanoTrak support software offers a series of motor search algorithms for this first light detection. Although used primarily for aligning optical fibers and integrated optical devices, the NanoTrak is ideal for automating just about any labor intensive alignment task, such as waveguide characterization, fiber pigtailing of active and passive devices, as well as a multitude of other R&D applications.

The NanoTrak is supplied with an Infrared wavelength (InGaAs) detector (NTA007) and a PIN diode SMB input for use with external detector heads. A visible wavelength (Si) detector (NTA009) is available separately as detailed below.

Principle of Operation

During the auto-alignment process, the NanoTrak® uses gradient search algorithms to locate the direction of a peak signal. This operation is similar to that of a compass finding the north pole. The sensitivity of the search is such that even far away from the peak signal, where there are small power gradients, the NanoTrak can decide in which direction the peak signal is located. This information is then used to make positional corrections via the attached high speed piezo actuators without having to map or search a large area.

In the proximity of a peak signal, the signal gradient seen is much smaller, indicating that smaller positional correction is required. When peak signal is reached the gradient seen changes to zero, indicating that no positional correction is needed.

The dynamic behaviour of the NanoTrak allows it to continue the alignment process indefinitely. Should the alignment change, the gradient search will detect the change and make a corrective move.

Typical Application Example (Optical Device Alignment)

Optical power transmission through any system under alignment can be described as a Gaussian coupling. Coupled power lowers as a function of distance relative to the aligned position (dependent upon device). Discrete power level alignments can be thought of as positions about the ideal coupling position, where the distances from the aligned position are equal. These discrete power alignment positions form concentric circles. These concentric circles represent the power contours and can be thought of as the gradient contours of a hill on a topographic map.

By detecting the gradient of the power at any given position, the NanoTrak can adjust the position until the power is maximized and the gradient becomes zero. This is achieved by scanning over the contours in a circular path to establish the direction of the signal maximum on the circular trajectory. The origin of the scan circle is then moved in the direction of the signal maximum.

Continuous active alignment can be used to maintain alignment, or the search algorithms can be halted for next step assembly or R&D operations.

Thorlabs offers two platforms to drive our wide range of motion controllers: our Kinesis® software package or the legacy APT™ (Advanced Positioning Technology) software package. Either package can be used to control devices in the Kinesis family, which covers a wide range of motion controllers ranging from small, low-powered, single-channel drivers (such as the K-Cubes™ and T-Cubes™) to high-power, multi-channel, modular 19" rack nanopositioning systems (the APT Rack System).

The Kinesis Software features .NET controls which can be used by 3rd party developers working in the latest C#, Visual Basic, LabVIEW™, or any .NET compatible languages to create custom applications. Low-level DLL libraries are included for applications not expected to use the .NET framework. A Central Sequence Manager supports integration and synchronization of all Thorlabs motion control hardware.

Our legacy APT System Software platform offers ActiveX-based controls which can be used by 3rd party developers working on C#, Visual Basic, LabVIEW™, or any Active-X compatible languages to create custom applications and includes a simulator mode to assist in developing custom applications without requiring hardware.

By providing these common software platforms, Thorlabs has ensured that users can easily mix and match any of the Kinesis and APT controllers in a single application, while only having to learn a single set of software tools. In this way, it is perfectly feasible to combine any of the controllers from single-axis to multi-axis systems and control all from a single, PC-based unified software interface.

The software packages allow two methods of usage: graphical user interface (GUI) utilities for direct interaction with and control of the controllers 'out of the box', and a set of programming interfaces that allow custom-integrated positioning and alignment solutions to be easily programmed in the development language of choice.

A range of video tutorials is available to help explain our APT system software. These tutorials provide an overview of the software and the APT Config utility. Additionally, a tutorial video is available to explain how to select simulator mode within the software, which allows the user to experiment with the software without a controller connected. Please select the APT Tutorials tab above to view these videos, which are also available on the software CD included with the controllers.

These videos illustrate some of the basics of using the APT System Software from both a non-programming and a programming point of view. There are videos that illustrate usage of the supplied APT utilities that allow immediate control of the APT controllers out of the box. There are also a number of videos that explain the basics of programming custom software applications using Visual Basic, LabView and Visual C++. Watch the videos now to see what we mean.

Response from Ben at Thorlabs: Thank you for your product feedback. You can download our new Kinesis software Motion Control software from the following link. Here you can also find further links to resources including example code as well as links to our legacy software package, APT. https://www.thorlabs.de/software_pages/ViewSoftwarePage.cfm?Code=Motion_Control

I finally succeeded in making the system work. It works very well. The software interface is very intuitive and efficient. We are going to save a lot of time during the numerous optical alignments.

Response from Mike at Thorlabs: I am glad to hear that you have solved the problem and we appreciate your feedback on the software interface. Please feel free to contact us if you have any further questions.

We just acquired a BNT001/IR system. I installed the software downloaded from the net successfully (no CD delivered with the system), installed it on a windows7 os pc, re-started the pc after connecting the BNT001/IR and couldn't see the user interface when using the APT-user software. Can you help me with this big problem?
msoulby  (posted 2015-06-16 03:45:45.0)
Response from Mike at Thorlabs: If the user interface does not appear there are a few things that can typically cause this. 1) Please ensure all USB cables are connected prior to powering up the controller, this is to help ensure USB communication is established correctly. 2) Check that the simulator mode is disabled in APT config, having this enabled accidently will prevent you from using the actual unit. 3) In APT User if the interface is not displayed you can check the View menu and then expand the 'graphical panels' sub-menu, in here you will be able to open or close any active devices that are currently connected.
