We present a telecentric design to obtain constant magnification with long axial scanning range in optical sectioning microscope. A Moiré lens is designed and used for this purpose. Design principles of our system are explained through mathematical expression and simulation results are provided for different conditions.

 

A cost effective optical design for colorimetric pyrometer was developed for laser-based additive manufacturing facility. Equipped with diffraction gratings and fiber array element, the colorimetric pyrometer has its robustness in sensing wavelengths and number of channels which is adaptive for characterizing thermal radiation from mixtures of black/gray bodies.

 

This study proposed a novel common path linear encoder. By combining with double-diffraction, interferometry, grating interferometry and common optical path techniques, the system can precisely measure in-plane displacement, while having the advantages of high sensitivity, high stability, high tolerance and has been miniaturized successfully.

 

In this work, we proposed a plasmonic Huygens metasurface with a state-of-the-art circular polarization conversion efficiency beyond 50% at telecom wavelengths. We highlight the feasible applications of our high-performance metasurface via demonstration of a beam deflector and a focusing metalens.

 

In this paper, we demonstrated a hybrid of optical fiber and free-space optics (FSO) for optical access networks. The experimental result proves that the hybrid of 25 km SMF with free space optic link increases the communication coverage range with a reasonable performance.

 

We have designed precise and fast Gated Recurrent Unit (GRU)deep learning model to detect the Bragg sensor wavelengths from the reflected overlapping spectra within the sensor network.The performance of the proposed model is good, even when the FBG sensor number is increased and the spectra is completely overlapped.

 

he plant water content changes, it also changes the chlorophyll concentration. Therefore, we study the use of chlorophyll fluorescence to combine the fiber and improve the previous structure. By fixing the fiber to the surface of leaf to determine the water content by sensing the change of chlorophyll fluorescence.

 

In this study, a special lampshade with a different structure is used to generate a UV LED inducing mosquito system. UV LED uses a specific wavelength of light (365nm UV LED) and matches the black appearance, as well as a solar energy-saving switching device, which maximizes the incentives. .

 

Smart phones equipped with biometric systems have become a trend. Fingerprint recognition is most common in biometrics. We propose a novel concept to design a full-screen optical fingerprint recognition system. The principle of optical fingerprint recognition mainly requires the calculation of Fresnel equation.

 

This study uses Solidworks for optic to draw and simulate a lens package for LED head light. This lens shape is made from an ellipse around a circle. By adjusting the size of the circle and the ellipse appropriately, the best with the latest head light regulation ECE R113.

 

A CGH component is designed for testing a large aspheric mirror as a part of its manufacturing process, with assist features are to assist in proper alignment to minimize alignment error.

 

Because of the long detection time and the generation of consumable waste liquid. Our developed is to integrate optical detection technology, IoT system, cloud construction and AI algorithm to develop an online concentration analysis system of one ion (copper, nickel, iron, chlorine), which is an important application for smart manufacturing.

 

We proposed a method for small polarization rotation measurement that is based on the use of a half-wave plate and a high-stability common-path heterodyne interferometry, When the azimuth angle at 22.5 degree of a half-wave plate, the phase has a distinct change caused by the the incident light.

 

This research is a headlight simulation using diode lasers combined with a Digital Micromirror Device (DMD). Use fast axis and slow axis collimator (FAC/SAC) to collimate the diode laser. Establish a lens (LENS2) to enlarge the light projection angle to comply with ECE R113 Class D, E high beam regulations.

 

In this study, a projector type headlamp using LEDs is proposed to be the vehicle lamp with integrated low-beam and high-beam light. The design of low-beam LED headlamp with a top ellipsoidal reflector and a baffle plate is used to achieve a LED headlamp with a low-beam cutoff line.
