Problem:

Acoustic scene analysis is the process of interpreting audio information from multiple perspectives. Information about the environment is collected via a system consisting of multiple microphones. Using a microphone array, we can accomplish this by gathering audio information from multiple perspectives.

Solution:

In our project, we plan to design and build a microphone array module that can connect with similar modules to form a scalable array with numerous sensors. The system will be reconfigurable and at least somewhat portable, so that data can be collected in real-world environments and with various configurations.

Our system will contain these parts:

1. Detection modules - For each module, we will use an array of sound sensors. These sensors will be able to detect the location of the incoming sound and then feed their outputs into the data processing unit.

2. Data Processing Unit - This unit will take in the data from all of the modules and keep track of the position of the sound. It could also perform some digital signal processing on the data in order to refine the data

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
