Fiber Ring Laser-Based Displacement Sensor

IEEE Photonics Technology Letters, 2016
We reported an erbium-doped fiber ring laser (FRL) displacement sensor based on a single-mode fiber (SMF) loop tied into the laser cavity. The proposed fiber loop structure acts as the sensing head as well as the filter of the FRL. A good linear relationship is obtained both in principle and in experiments between the displacement of one end of the ...

Integrated micro-laser displacement sensor

Proceedings IEEE The Tenth Annual International Workshop on Micro Electro Mechanical Systems. An Investigation of Micro Structures, Sensors, Actuators, Machines and Robots, 2002
A new integrated optical microlaser displacement sensor including a Michelson interferometer was developed and its feasibility as a measurement device was confirmed. It can measure the relative distance traveled against an outside reflective mirror. The measurement resolution is expected to be on the order of 0.01 /spl mu/m.

Laser based smart displacement sensor

SIcon/01. Sensors for Industry Conference. Proceedings of the First ISA/IEEE. Sensors for Industry Conference (Cat. No.01EX459), 2002
The paper presents a displacement measuring system based on one optical emitter (laser diode), two optical sensors and on a smart structure used for sensor data processing. The system is designed around the PIC16F877 8-bit microcontroller that powers the sensors, acquires data from the sensors and performs the intelligent processing based on a neural ...

Measuring leg ulcers using a laser displacement sensor

Physiological Measurement, 1994
A non-contact method for the measurement of a skin ulcer's area and volume has been developed. A commercially available laser displacement sensor is scanned across the ulcer's surface to produce a displacement image. From this image the healthy normal skin's surface is reconstructed and the area and volume found.
