Fiber Optic Sensor for CubeSat
Channel: UNLVECE
Date: 2018-02-17

The Fiber Optic Sensor for CubeSat is a sensor module designed to be implemented in the future for use in UNLV’s CubeSat project. Compared to conventional angular sensors such as gyroscopes, the fiber optic sensor boasts higher reliability and precision. Fiber optic sensors do not use moving parts. This is a huge leap in reliability regarding to astronautical engineering where repairs are not an option once a satellite is deployed. Ultimately, the fiber optic sensor accomplishes the challenge of angular correction and alignment in space where user controlled steering would be delayed and error-prone.

This fiber optic sensor pulls from larger fly-by-optics applications in planes that take advantage of high data transfer rates all the while remaining discreet and low power. Using a grating mirror and multiple fiber channels, the fiber optic sensor can determine angular moment by detecting the differences in intensity between internal photodiode sensors.

In the scope of UNLV’s CubeSat project, the fiber optic sensor seeks to be modular and lightweight with the possibility of integration into other projects in the near future. Fiber optic sensing is a developing technology with many facets of application for home and industrial use. Fiber optic sensors can be used in tandem or entirely replace conventional CMOS chips thereby saving space and power.
