Leveraging the ZOS-API to compute background levels in an infrared imaging system​

Brian Catanzaro, Sole Proprietor, CFE Services


Infrared imaging can be susceptible to noise from infrared radiation produced by blackbody radiation. Quantifying this background radiation is critical to designing the system to operate at the proper temperture while maintaining an appropriate SNR. During this session, we will discuss using non-sequential ray tracing and the OpticStudio ZOS-API, the view factor and area. I'll also share how solid angle of emission from "warm" components in the system can be modeled to minimize the impact of background radiation and maximize SNR.

Human oral mucosa modeling in OpticStudio
 

Sharadindu Banerjee, Optical Engineer (R&D), Tishya's Medical Device Development Pvt Ltd

In modern days a scientific experiment is validated by observing results of a given set of inputs and the larger the inputs, the higher the accuracy of the experiment. During this session, we discuss the simulation effects of a three-layer oral mucosa model we created using Zemax Opticstudio. Never implemented in OpticStudio before, we have successfully simulated the oral mucosa model and our results show the important optical properties of different layers of the oral mucosa. Our model can be a useful tool in areas like bio-photonics and tissue modelling.Our model can be a useful tool in areas like biophotonics, tissue modeling and to train ML algorithms.

Using Python and the ZOS API for alignment simulations of a catoptric spectrograph collimator 

John Capone, Lead Optical Researcher for HARMONI Spectrographs Sub-system, University of Oxford

HARMONI is an integral field spectrograph that will be commissioned on the European Southern Observatory’s Extremely Large Telescope in 2025. We have been particularly concerned about the alignment procedure of the spectrograph collimators, as they are comprised of three off-axis, aspheric mirrors which lack a common optical axis. For an initial demonstration of this method, I have written a Python code which uses the ZOS application programming interface (API) to simulate the collimator alignment process. The modelled systems include manufacturing errors, account for the uncertainty of values reported by mirror manufacturers, and simulate the CMM and interferometer alignment steps. Nearly all of 1000 instances meet our requirements after two iterations of the optical alignment, and all were found to satisfy our requirements after five iterations.

GPU-optimized light-tissue simulation integrated with the OpticStudio API

Alex Margiott , Senior Scientist, Tripple Ring Technologies, Inc.


Triple Ring Technologies’ proprietary software, ‘Monte-Carlo Integrated (MCI)’ provides fast and accurate modeling of photon transport through tissue, with a variety of outputs available for analysis. MCI uses objects that are placed directly in the Zemax OpticStudio environment, allowing a full integration between the physical instrument optical model and tissue simulation outputs. Within MCI, the user can model a complex layered medium, with different optical properties on a per-layer basis. Rays quickly travel through the medium and can be re-launched back into the Zemax OpticStudio environment via the OpticStudio API for continued progression through collection optics. See the software in action during this high-energy presentation!

High-resolution holographic image synthesis for augmented and virtual reality eyeglasses 

Praneeth Chakravarthula, PhD Student, University of North Carolina at Chapel Hill

This session will present a new family of techniques for computer-generated holography (CGH), collectively referred to as “Wirtinger Holography”, that promises unprecedented capabilities for future displays, including eyeglasses-style near-eye displays for augmented and virtual reality. CGH is often associated with noisy monocolor imagery with low contrast, making it impractical to use. Wirtinger holography techniques overcome several of the challenges related to both hardware limitations and existing-phase-retrieval methods, making it one of the most promising techniques for superior holographic displays.

Advanced Gaussian beam analysis using skew rays 
 

Paul Colbourne, Director, Optical Switching Technology Advanced Research, Lumentum

In this talk I explain how to generate a ray set which has a ray density equal to the intensity distribution of a Gaussian beam at all points in space, including the waist. This ray set can be used to compute the field profile and fiber coupling efficiency. A variation of this ray set has a uniform ray density below the beam radius and zero density above the beam radius, and this ray set is particularly useful for visualization of generally astigmatic Gaussian beams on layout diagrams.

Designing a low-cost dust sensor using non-sequential techniques and optimizing it’s response to particle flow using a ZPL macro technique.

Kyle Johnston, Owner, Luminart Labs, LLC

The first part of this talk reviews the non-sequential techniques that were used to design a functional prototype of a low cost consumer grade airborne dust sensor. The design utilizes a radiant source model for the LED and filter string analysis was very useful in configuring the mechanical package for optimum signal light with minimum stray light. The signals that are generated by sensing systems that have dynamic flow characteristics can be challenging to predict and difficult to optimize. The second part of the talk discusses a technique that was developed using a volume detector and a ZPL macro to characterize the illumination and detection characteristics of the system separately, allowing the dynamic system response to particle flow to be efficiently modeled.
