Fresnel zone plate and its application in optical acceleration sensor
A method to design and prepare a Fresnel zone plate for all-optical type acceleration sensor was proposed
and the design principles and parameters of the Fresnel zone plate was introduced. The maximum and minimum theoretical radii of the wave band plate were 494.19
m and 78.11
m respectively with the size precision in micron level. The micro-nanofabrication process technology of the zone plate was developed. Then a high-quality zone plate was successfully fabricated. The boundary of the zone plate was smooth and complete
thus proving good focusing and imaging properties. Finally
an all-optical type acceleration sensor based on the zone plate diffractive properties was developed and tested. In terms of the output curves from the test
it shows that the output of the sensor proves a good linearity with the acceleration and the sensitivity is 0.033 V/
g
. The sensor guides light with optical fibers instead of electronic components
which provides good resistance to electromagnetic interference and promising applications in harsh environments.
