Sound Deceleration and Acoustic Absorption Towards Building a "Flute Mute"
Ayumi Yuasa
With the goal towards creating a prototype that helps lower the volume of flute playing for practice and orchestral purposes, my project focused on implementing ways to decelerate and absorb sound waves in the flute headjoint (the primary audio source of the flute).

Mandrel-In-Motion
Alessandra Sauro, Alexander Kaufman, Emily Volk, Tae Ryoo
This project sought to help ORAFOL improve the uniformity of their electroformed reflective materials and subsequently reduce their required grinding time. Trials were conducted to test the "Mandrel-in-Motion" theory, which hypothesizes that movement of the mandrel during the electroforming process will sufficiently disturb the ion transfer by rapidly changing the electric field lines, resulting in a more uniform thickness. The project involved meaningful design of experiments, characterization of a motor and rotating arm system, and methods to estimate fluid velocity.

FaFactors Influencing the Injection Molding of Isoplast® 302 EZ Resin
Seth Edwards, Claire Evans, Collin Larkin, Amelia Moriarity
Harbec Inc. uses Lubrizol Isoplast® 302 EZ resin to extrude into fuel filter caps, but noticed that some batches had higher rejection rates than others. Our charge was to find a way to differentiate “good” and “bad” lots of resin prior to drying and extrusion. Through a series of tests, we were able to produce the promising results that the “good” resin may contain more elemental tin, which could act as a stabilizer that reduces the lot’s rejection rate, in addition to the fact that COA analysis showed that there is a correlation between melt flow rate and rejection rate.

Optimization and Characterization of Biochar-Polystyrene Composite
Charlotte Berg, Callum Breene, Nisha Divan, Benjamin Gleed
The objective was to optimize a process for creating a composite of Biochar and expanded polystyrene for use as a building material in developing countries. Improvements made to the original process included a solvent change, Biochar grinding and sieving automation, and a vacuum pump addition to degas samples. It was observed that samples contained void spaces, were hydrophilic, and that increasing toluene concentration both lowered a sample’s glass transition temperature and decreased mechanical strength –important characteristics when deciding on potential applications.

Relative Position Locator
Abigail Eberts, Christopher Granata, Brianna Herron, Natalie Jara, Steffen Jensen
A common issue among first responders is the inability to locate teammates in emergency situations (i.e. firefighter finding their partner in a burning building). Our project solves this problem, using a radio, trilateration calculations, RSSI values, and compass headings simultaneously to calculate the position of a teammate relative the the user. The first responder will be able to identify where the teammate is using an LED ring-- the location of the LED provides the direction of the teammate relative to you along with a color to identify approximate distance.

Optical Exhibit for RMSC
Haley Knapp, Stephen Chess, Zilong Li
We created and exhibit for the Rochester Museum & Science Center for the 2020 Women in Science exhibition. Our project is inspired by Katherine Burr Blodgett who pioneered anti-reflective coating(invisible glass). By using the concept of index matching, we created our own "invisible glass" by immersing a glass into an index matching liquid through the use of a motor. The exhibit is educational and interactive for the general public.

Analyzing Mid-Spatial Frequency (MSF) Error in Monolithic Freeform Telescopes
David Henry Lippman, Matthew Page, Woo Kim, Kevin Kuyk
Mid-spatial frequency (MSF) figure errors are artifacts introduced to optical surfaces when performing sub-aperture grinding and polishing. For three monolithic freeform telescopes being fabricated at Optimax, we developed our own state-of-the-art model for analyzing the effect MSF errors have on optical performance. Empirical measurements have validated our model’s accuracy and have allowed us to perform sensitivity analysis and tolerancing of the monolithic designs for MSF errors.

Team VISION
Ali Hashim, Perry Wang, Weidi Liu, Diego Martinez
The goal of this project is to develop a visual image simulation tool for DigitEyez to provide accurate prescriptions for eye care while reducing the time, cost, and error currently associated with eye exams. The Visual Image Simulation tool will aid ophthalmologists to give more accurate prescriptions. The VIS tool will be used in conjunction with DigitEyez’s proprietary algorithm, which will determine the ideal prescription of the patient without subjective measurements.The patient’s feedback from using the VIS tool will confirm that the prediction is correct or not.

Split-Step Beamlet Method for Modeling Nonlinear Frequency Mixing
Jonathan Heinz
This project aims to create a numerical method for modeling nonlinear effects through complex crystal geometries that is flexible enough to handle non-planar surfaces and misalignment without additional effort on the part of the laser systems designer. This is accomplished with the help of existing coherent ray propagation functionality within the non-sequential ray tracing software FRED.

Coherence Length Measurement Device
Pellegrino Conte, Lei Ding, Maxwell Wolfson
The goal of this project was to ensure the proper function of the multi-wavelength sources used by semiconductor manufacturers in their optical alignment sensors, by developing a coherence length measurement device. Our team has developed a modified Michelson interferometer system that utilizes a reflective grating in one arm and a rotation stage that can be directed at multiple mirrors in the other arm in order to meet this goal.

 Designing a New Imaging System for Training Surgeons
Katie Armstrong, Nora Lane, Jeffrey Tsao, Joseph Kelly
Our project is a new optical illumination and imaging system, to be used by doctors in the Urology Department, when they conduct practice surgeries for removing kidney stones. Our design utilizes Near Infrared light rather than X-rays, so that the doctors can conduct these practice surgeries in a safer environment.

Lens Design for Photoacoustic In-vivo Imaging Probe
Ryan Sauer, Daniel Graney, Nancy Aguilera, Yichen Gu
The goal of this project is to design, fabricate and test an acoustic lens system to improve the performance of the in-vivo thyroid photoacoustic imaging probe. We focused mainly on reducing the attenuation seen within the lens, which resulted in apodization of the signal received at the sensor, by use of Fresnel lens structure. The lenses were 3D printed on a high resolution printer in the Rettner Fabrication studio and then tested over various depths of field.

Classical MTF-Based Wavefront Sensing
Brandon Dube
I have performed a theoretical and experimental study into the effectiveness of using Tangential and Sagittal (aka classical) MTF measurements as inputs to a wavefront sensing algorithm. This includes doing more than 3,000 simulations for statistical analysis and multiple experimental trials. The projects' conclusion is that the loss of Fourier phase caused by using MTF is not very important, however the azimuthal undersampling of only having T&S MTF breaks the algorithm for non rotationally invariant aberrations.

Profilometry: A tool for Tuberculosis Detection
Sze Wah Lee, Coco Yang, Rebecca Silver, Madilyn Beckman
The TB team utilized profilometry, an optical method, to meet the basic criteria requested by the customer. This design explores the physical traits such as area and volume of the skin reaction to the PPD injection. This solution is similar to the current medical procedure, but will eliminate the subjectivity of measuring the spot by hand or simply judging size via the human eye.

Single Emitter Fluorescence in Plasmonic Gold Bowtie Nanoantennas
Jeremy Staffa
Cutting-edge quantum technologies often demand single photons as the carrier of information. This project aims to address the source of said single photons. The single photon emission properties of semiconductor quantum dots and NV centers in nanodiamond were investigated as well as the effects of plasmonic gold bowtie nanoantennas on the single emitters.
