A PANDA ring resonator circuit has been applied to the measurement of muscle actions, measuring signals created by facial muscle contractions. A system, which is called the Optical Muscle Sensing System, was developed which uses sensors to measure the mechanism of facial muscle contractions and the strength of contraction and degrees of perturbation of the facial muscles that are used directly for each facial gesture. The signal data was obtained from the simulation of the facial gestures and this data was applied in the classification of the facial gesture signals of each particular gesture. Facial gestures include blinking, smiling, grimacing and various other contortions of the face which may imply emotions and are part of normal human communication. Understanding of these mechanisms will be useful and applicable to facial rehabilitation services.

We propose a micro-optical sensing system for muscle contraction and movement measurement, in which a PANDA ring resonator type is used as a basic optical device called Muscle Optical Sensor (MOS) system. The MOS system consists of an optical add/drop filter which is connected to two micro-ring resonators, of which the right ring is a sensing unit and the left ring is a reference ring. The key contribution of this paper is a novel approach for measuring contraction and transfiguration of muscles by using the small scale optical device. The contraction or transfiguration of muscle is directly perturbed into the sensing unit, which changes the optical path length. These resultant changes in wavelength (∆λ) are measured and obtained by the difference of the sensing and reference signals. The experiment was conducted by using the MATLAB and Opti-wave programs, which indicated that the changes in the sensing radius were associated with the change in wavelength. The results and techniques can be used beneficially for muscle sensing applications. 

“…Till date, the 3D imaging microdevice has been widely research and investigations, especially, when the nanotechnology is involed, where there are many researches in both theoretical and practical works . Recently, the modified optical add‐drop filter has become the promising device in many applications . Such a device is configured as a microring resonator, which is formed by the linear and nonlinear microring resonators, where one of them is formed by nonlinear semiconductor material and known as a Panda ring resonator , which was constructed by a standard optical add‐drop filter within the micrometer scale device, in which the nonlinear coupling effect was introduced by the two nonlinear side rings, where the ring radii were within the submicrometer range, the nonlinear material is normally used AlGaAs/InP , from which many applications could be involved, for instance, in communications, sensors, nanomedicine, drug delivery, and nanotechnology .…”

A single eye three‐dimensional (3D) imaging perception using a single 3D imaging pixel is designed and manipulated, which is the interesting device configuration that can be used for various applications. The device configuration is consisted of double conjugate mirrors that can be vertically fabricated, which can be used to form the 3D image using a single pixel configuration, from which the large area device construction is also possible. By adjusting the microconjugate mirror parameters, then the matching between both microconjugate mirrors can lead to obtain the required 3D images. Results obtained have shown that the 3D image outputs can be achieved and used for 3D pixel imaging. The 3D image output can be confirmed by the four‐wave mixing output balancing profile, which is achieved. In applications, the large area 3D images can be constructed using the large area 3D imaging device, from which the large area can be coverage by the microconjugate mirror array, which can be useful for various applications. © 2015 Wiley Periodicals, Inc.
