P11565: ITT Mirror Steering System

Concept Design Review Documents (SD I)

Table of Contents

Project Background

This project, commissioned by ITT, is to design a prototype beam steering mechanism to be used in aerospace applications, on planes or satellites. The projection of a laser beam can be manipulated by the mirror, system of actuators and sensors we design.

The mirror is moved along two axes using electro-mechanical components and is to fit inside a 3in diameter, 3in long cylinder.

We have narrowed down the mounting design for the mirror, as well as which design of voice coils to use.

Problem Statement

A mirror steering system is needed to outperform current commercially available devices in one or more performance specs, while maintaining low power dissipation. ITT would like a prototype they can refine for space applications in their laboratory.


Design actuators that convert electrical energy to mechanical position to meets customer needs and specs including speed, accuracy, and precision.

Develop a functional, efficient prototype while producing documentation of all design steps for future development.

Name Discipline Role / Skills
Dr. Alan Raisanen Faculty Guide - Will work closely with the team on an on-going basis to facilitate success.
Michael Obrien ME Industry Consultant - Will work closely with the team on an on-going basis to facilitate success.
Matt Manelis ME Project Manager - Responsible for maintaining project schedule, coordinating project tasks, and systems integration. In addition to having strong leadership and communication skills, the project manager should have taken the DPM course.
Katie Hall ME Lead Engineer - Responsible for establishing realistic compromise device architecture and engineering parameters to meet desired performance objectives using commercially available components such as actuators and power supplies.
Matt Manelis / Katie Hall ME Mechanical Engineer - Responsible for designing and implementing a hinged mirror assembly with actuators for positioning. Basic familiarity with modeling packages, such as ANSYS or COMSOL, is a must.
Ben Geiger EE Electrical Engineer - Responsible for implementation of the mirror actuators and position sensors, along with any power supplies required to operate them. Knowledge of electrical engineering (analog), and basic familiarity with position/velocity sensors and electromagnetic or piezoelectric actuators is required.
Nurkanat Suttibayev IE Test Engineer - Responsible for design and implementation of a testing plan to demonstrate the performance of the prototype mirror steering device. Demonstration of the device will require driving it with proper electronic signals, along with the measurement of beam jitter, position, accuracy, and power consumption.
Andrew Bishop EE Integration Engineer - Responsible for assisting the Electrical and Test Engineers with the necessary support, as well as working closely with the Mechanical Engineer to ensure interfaces between electrical and mechanical components are valid.
