Space Phonics   

 "Space" or "Universe" is a final fronteer asmany people said.
Then the space is also important field for photonics. There are so many things can be done with photonics technology and so many photonics technologies required for "space" application.


 Space industry

Recent progress in many engineering field made "space technology" much advanced. Most of industrial devices become smaller and more functional with the size. Furthermore, they are very efficiant to avoid large energy consumption.

It is the time for us to utilize the engineering progress to the space application. Small satelite system is the one of the application.50cm ize with 50kg to 100kg of weight is the target size of such small satelite system. Someone at a space related conference said that the small satelite is like a cell phone containig camera, GPS, transmitter, sensors, and battery, all coontroled with a tiny CPU. The small satelite has similar configuration except it has to fly in vacule and high and low temperature enviroment.

Another important situation is that the small satelite can be transfered to the space within a well configured rocketcargo priventing typical big vibration during the launch. Thus the satelite is not require strong structures which can servive in the space without any gravity.

 Space Photonics

The small stelite system requires good devices to make the system compact and functional. We are working for a telescope system with large diameter of concave primary mirror and short telescope structure. As the size of the satelite becomes smaller, the telescope having good spatial resolution must be compact enough. That is a challenge we need to do with current photonics technologies.

Small telescope

 We work with Harada fine mechanics company inJapan to make the small telescopes to be commertialized for sale.

On Dec.2012, there was an exibition called JA 2012. Namely, Japan Aeroscpace Expo 2012.
We have demonstrated a proto-type of the telescope with 200mm diameter and 200mm
length incorporating seberal cameras to measure variou information of the earth from the space.


New material for the space telescope

 New ceramic concave mirror

Under a collaboration with the graduate school for photonics, we have developed a new type of ceramic concavemirror with is thermally stable in the space. The ceramic does not expand much at around room temperature tested by a wavefront analysis system.
