Next Generation Edge Sensor Design for Segmented Primary Mirror
Adaptive Optics Systems
In this Phase I effort, SY Technology, Inc., proposes to design,
build, demonstrate, and deliver to NASA an integrated circuit edge
sensor prototype for aligning subaperture surfaces of adaptive
optical components. The innovation in this SBIR drastically reduces
the unit cost of existing edge sensor devices by converting
discreet component technology into low cost, easy to assemble and
calibrate, highly accurate, very low
noise, integrated circuit devices. By implementing existing edge
sensor technology in integrated circuit designs, the complexity
and cost of adaptive optical systems will be greatly reduced.
These types of adaptive optical systems have wide application
within NASA. Reduced cost adaptive optical systems make
commercial power beaming concepts, such as SELENE, more cost
effective, as well as making large total aperture adaptive
optical systems more available for ground-based astronomy.
In addition, a number of dual-use applications are evident for
this position sensing technology. These application include:
position sensing for laboratory instrumentation, materials
testing, and for weight and pressure measurement devices.
Preliminary discussions with Lockheed show great potential
commercial interest in this innovative concept.
The key factor driving the excellent commercial potential of
this device is that existing edge sensor technology will
simply be implemented through inherently low cost standard
integrated circuit technology. Potential applications for this
* Edge sensor for power beaming technology such as SELENE.
* Edge sensor for astronomical telescopes that utilize
adaptive optical techniques.
* Position sensor technology for laboratory position
measurement instrumentation. This non-contact position
measurement device has very high resolution and accuracy.
* Position sensor for extension meters for use in materials
* Precision pressure/weight sensor when combined with
linear spring and digital readout.
