Project 1:

The team choosing this will be better off if:

They are highly motivated.

They Love intricate detail.

They have CNC training due to the detail

and compact nature of the components as

an assembly.

They are well organized and willing to meet

on a regular basis.

Past Work: The turning mirror project

Team 5 Fall 2009, did a wonderful job and the design is ready for critical review.

This is a very complicated device and will require considerable review

with small modifications to the mechanical structure before moving on

to fabrication.

Project 1: continue TEAM FRED redesign effort for turning mirrors

From MAE 490 Fall 2009, Led by Cheryl Rose

“The” FIX?

• Innovative

• Effective

• Ergonomic

• fully functional

design

• Can we add rotation to the mirrors?

• Can we fabricate such an animal?

• Tolerances, what about tolerances?

• Needs Further Evaluation / fabrication

• add rotation to design

Ground floor project

• Design/fab mechanical fixture to Mount spindle

• Lightly mount spindle to machine/Tram

• Measure motion vibration accuracy linearity

• Specify lubrication material & cleanliness

Project 2:

Many thousand pounds

This type of optical system has myriad uses in the field

of remote sensing. It is also scalable from tiny to very

large. Might be a great use for the rapid prototyping

machine in MAE shop, work out the kinks before going

to production.

Project 3: Design a chassis for a Mersenne telescope.

This telescope would be on the order of 5 inches diameter and 6 or 7 inches long.

We would require the design to be using light-weighting techniques as well as the

use of flexures for the secondary mirror alignment.

The design would require a pocket in the chassis for the primary mirror mount as well

as a support structure that does not interfere with the clear aperture of the telescope (

really a telecentric beam expander).

the alignment tolerances are quite tight for the optical elements and if the chassis is

designed to these tolerances could cost considerable money to fabricate. However if

the design simply accounts for micro positioning of the secondary mirror, as one

would do by the use of flexures, the chassis would have fairly loose tolerances and

could be quite cheap to fabricate.

This project will require the fabrication of two optical elements, perhaps the CAO

could fund this part; maybe even use an OSE student team for the design verification

and specification

Project 4: Thin disk laser Folded Resonator design

Laser resonator is Currently 1.41meter total length

Want to fold to 0.3meter

• Have new optics, cavity calculations complete

• Have some tiny mounts

• Have some ideas

• Need mechanical designs

• Need fabrication of components

• Need assembly and test

Want at least 60W out of laser, that’s what we have now

Only its 4 feet long….

Project 5: IR collimator test system for evaluation of camera lenses on

The giga-pixel camera system.

Design system level

Station for collimator.

Work with Dave Pollock

for details.

We have some hardware

And basic designs

already in place

Optical pickups are just now being introduced for amplification of the strings and the signal is

simply sent to an amplifier

Past work: Acoustic guitar optical pickup.

a series of diodes illuminating the guitar

strings.

one pickup detector

for each string

This device would monitor the strings and when one string was struck, the processor ( ECE

project) would listen for the frequency of the note and output the fret pressed for each string

This would allow a guitar player to play

whatever he wants and the output would ,

through a computer GUI, write down the

tablature (notes) for the piece that is played

in near real time

Patent Potential

This device will be self contained, will mount to the

guitar in such a way as to not interfere with the

playability of the guitar and will have no connection to

the amplifier, at least not yet.
