R & D pour la défense Canada - ValcartierInnovation et Impact

1. Deliver surveillance systems that respond to military requirements:

• high resolution,• smaller size and weight, • low power, etc

2. Develop a canadian capability for high end night vision3. R&D: Exploit and develop new sensor materials or design

that lead to novel electro optic devices

Visible NIR - SWIR MWIR LWIR

NIR-SWIR (Day/Night)• InGaAs: Low resolution

• close to human natural visual perception

MWIRInSb & MCT: Very sensitive, cooled, good

resolution

LWIR• MCT: Very sensitive, cooled, low resolution

• uBol: Gets better and better, • Very good target detection – hot spot

VO2 can switch reversibly from an IR-transparent to an opaque thin film when properly triggered.

This optical behavior is exploited here as a smart mirror that can modify the resonant cavity depth between the suspended thermistor material and a mirror patterned on the substrate, thereby altering wavelength sensitivity and creating a dual-band microbolometer.

Outputs/Deliverables:Validated concept, design, fabrication, analysis and simulation

capability for typical NanoSat MEMs propulsion system Development of MEMs components for an array-type propulsion

system incorporating solid rocket propellant.Development of micropropulsion vacuum thrust stand. Final report summarizing:

Requirements for propulsion for lifetime maneuvering of a typical 1.3 kg NanoSat

Viable MEMs design, including materials, and fuel.Experimental and numerical performance estimates.

Outcome:Capability to support DND, CSA, and Canadian industry for the

development of NanoSats including extending mission lifetime, formation flying for a cluster of NanoSats, and possible end of life positioning capability.

Capability to assess development of this technology around the world (tech watch, threats)

Nanosats are an emerging and disruptive technology. On board micropropulsion system is an enabling capability.
