This may be crucial when the application characteristics necessarily imply a simple and inexpensive sensor. These systems, where the estimation is mainly implemented in the digital domain, can generally benefit from the use of undersampling to reduce the digitizer and subsequent digital processing requirements. Consequently, simultaneous torsion and temperature measurement could be realized by detecting the envelope shift and fringe visibility of the spectrum.Ī wide range of measuring applications rely on phase estimation on sinusoidal signals. Additionally, the fringe visibility of the spectrum will change due to the fiber twist, and the test results reveal that the fringe visibility and twist angle perfectly conform to a Sine relationship over a 360° twist angle. The temperature sensitivity is calculated to be −17.99 nm/☌, which is enlarged over 12 times compared to that of the single Sagnac interferometer. The experimental results show that the envelope of the output spectrum will shift with the temperature evolution. The temperature and twist sensor based on the proposed interferometer structure have been experimentally demonstrated. The two inserted sections of HiBi fiber have different functions while one section acts as the temperature sensitive region, the other can be used as reference fiber. In addition, we checked the planimetric accuracy by bundle adjustments with GCPs.Īn optical fiber temperature and torsion sensor has been proposed by employing the Lyot-Sagnac interferometer, which was composed by inserting two sections of high-birefringence (HiBi) fiber into the Sagnac loop. Then, the positional accuracies without any GCPs (ground control points) were validated for hundreds of test sites across the world using various image acquisition modes. The workflow includes the boresight calibration, CCDs (charge-coupled devices) alignment and focal length determination, the merge of two CCD lines, and the band-to-band registration.
A set of images over the test sites was taken for two months and was utilized for the work. In this paper we present the geometric calibration and validation work of Kompsat-3A that was completed last year. Kompsat-3A’s AEISS-A (Advanced Electronic Image Scanning System-A) camera is similar to Kompsat-3’s AEISS but it was designed to provide PAN (Panchromatic) resolution of 0.55 m, MS (multispectral) resolution of 2.20 m, and TIR (thermal infrared) at 5.5 m resolution. If you are interested in actual logic, please refer the code.Kompsat-3A, which was launched on 25 March 2015, is a sister spacecraft of the Kompsat-3 developed by the Korea Aerospace Research Institute (KARI). withStyles HOC returns component with classes attribute and link your styles object to component. The magic happens in the last line withStyles. Index.tsx ReactDOM.render(, document.getElementById('root'), ) Īnd each child component looks like below. To use it, normally you provide theme in your root component which used React context API. With MUI, you can define your own theme and write CSS in JS. Snapshots of Material UI styled component with React Testing Library and TypeScript.

If you would like to know other topics of React Testing Library, please refer the articles below. So this article explains how to setup React Testing Library for Material UI styled component with TypeScript. However, because Material UI (MUI) styled component use HOC (Higher Order Component), setup is bit complicated. When it comes to frontend, React Testing Library is becoming popular because it’s easier to test React hooks compared with enzyme. It enables us to change codes more speedy with less bugs.
