TracePro

TracePro is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand TracePro rather than just read about it. In short: TracePro is a commercial optical engineering software program for designing and analyzing optical and illumination systems. The program's graphical user interface (GUI) is 3D CAD-based creating a virtual prototyping environment to perform software simulation before manufacture.

Key takeaways

TracePro belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TracePro to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TracePro from memory before moving on to harder problems.

Reference excerpt

TracePro is a commercial optical engineering software program for designing and analyzing optical and illumination systems. The program's graphical user interface (GUI) is 3D CAD-based creating a virtual prototyping environment to perform software simulation before manufacture.

History Developed by Lambda Research Corporation of Westford, Massachusetts, USA, under an SBIR grant from NASA, the program has been in continual development since 1994. NASA uses the program in its next-generation integrated design manufacturing approach as detailed in NASA's Spinoff magazine.

Markets TracePro is used in the aerospace, defense, lighting, display, biomedical and illumination markets. It has been used in many projects for designing and analyzing all types of optical/illumination systems ranging from stray light suppression in telescopes and cameras to biomedical applications to LED modeling and solar collector modeling. In the aerospace market, TracePro is best known for its stray light analysis capabilities. The program was used to analyze the FIRST Telescope, James Webb Space Telescope, the Mars Rover cameras, Long-Range Reconnaissance Imager (LORRI) and the Terrestrial Planet Finder Coronagraph.

The TracePro approach Users create geometry either by using the native TracePro CAD interface or by importing models directly from SolidWorks, Pro/ENGINEER, Solid Edge, Autodesk Inventor or other CAD product that exports IGES or STEP models. TracePro additionally has an add-in to Solidworks, RayViz. RayViz allows users to apply and save optical properties directly to their SolidWorks model and ray trace surface sources as raysets to visualize light propagation within Solidworks. To ensure data integrity, a single model is used by both TracePro for ray tracing and optical analysis and by SolidWorks for mechanical design and modifying optical material properties. With RayViz, users significantly accelerate the iterative design process. Users using optical design programs such as OSLO, Zemax or Code V can also import these models to create a complete optomechanical design using the built-in multi-document interface. After creating the optical-mechanical model users then create sources using built-in source wizards, import models from the bulb catalogs or import ray files created from measured data, measured by Radiant Imaging's ProSource Radiant Source product. Then rays are traced through the systems to find energy distributions on any surface or track volume flux through any space. Users can also simulate lit appearance of illumination or lighting systems and trace bitmap images through optical systems to check for uniformity, veiling glare, flare, and distortion issues. Thermal effects and stray light issues can also be simulated.

Compatibility TracePro works with other software products using a Dynamic Data Exchange (DDE) client/server interface. This enables the program to work with products such as MATLAB to create a multi-disciplinary environment. TracePro also uses the Scheme language as a macro language to extend the program's capabilities and provide automated analysis, optimization, and tolerancing capabilities. TracePro models geometry using the Kubotek Kosmos 3D Framework.

Editions TracePro optical software is available in three commercial editions:

Worked examples

Example 1 — a first encounter with TracePro

Start with the simplest possible case. Write down what TracePro claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TracePro before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TracePro ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TracePro

In research: TracePro appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses TracePro in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: TracePro is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1994 software, Optical software, Science software for Windows, so understanding it makes those chapters shorter.
In everyday life: Look for TracePro outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is TracePro in simple terms?

Why does TracePro matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study TracePro?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
