Project Desciption:
The coil gun constructed by groups in the previous semesters, Prof Reinhard and Chris Barth were able to design and implement the SCRs and related power circuits. Control systems for synchronizing of firing of the SCRs to accelerate the projectile through the barrel still needs to be implemented. There is also a need to design a user interface to operate the gun effectively.

Overview of proposed solution:
VCSELs (semiconductor lasers) couple with photodiodes have been installed on the barrel of the gun to accurately measure the velocity of the moving projectile. The data from these sensors will be used as inputs to a microcontroller/FPGA. An algorithm on the microcontroller/FPGA would give a trigger output to initialize energization of the magnetic coils on the barrel. We could also use a time-of-flight sensor to get an added set of data on the position of the projectile.
The UI would be implemented using a separate controller and an attached screen. It will show details of the shot such as power consumed, barrel velocity of projectile, etc.

Project Description

Computed Tomography, often referred to as CT or CAT scans, is a modern technology used for medical imaging. While many people know of this technology, not many people understand how it works. The concepts behind CT scans are theoretical and often hard to visualize. Professor Carney has indicated that a small-scale device for demonstrational purposes will help students gain a more concrete understanding of the technical components behind this device. Using light rather than x-rays, we will design and build a simplified CT device for use as an educational tool.

Design Methodology

We will build a device with three components: a light source, a screen, and a stand to hold the object. After placing an object on the stand and starting the scan, the device will record three projections by rotating either the camera and screen or object. Using the three projections in tandem with an algorithm developed with a graduate student, our device will create a 3D reconstruction of the object.

Hardware

• Motors to rotate camera and screen or object

• Grid of photo sensors built into screen

• Light source

• Power source for each of these components

• Control system for timing between movement, light on, and sensor readings
