a photodiode, and two holes that allow the light to enter through the disc and then bounce back through the holes and strike a photomultiplier tube (PMT) or transistor. This arrangement is used for even higher accuracy than the basic design, allowing for measurements in submillimeter ranges...
The observed differences in grain size measurements between optical analysis and EBSD analysis can be largely attributed to three phenomena: (1) individual samples may behave slighty differently due to differences in the effectiveness of etching (2) the grain size is heterogeneous over large areas ...
Having an absolute position immediately on startup is important for safety reasons in certain applications. There are two sub-types of absolute optical encoders: single-turn encoders give the absolute position within a 360° rotation (typically used for shorter distance measurements). Multi-turn ...
Field of view (FOV) is the open, observable area a person can see through their eyes or via an optical device, such as a camera. In the case of optical devices, FOV is the maximum area that the device can capture. In other words, it answers the question: "How much can the device ...
Frequently Asked Questions (FAQ) 1. What is data annotation or Data labeling? 2. What is annotated data? 3. Who is a Data Annotator? 4. What is a data annotation tool? 5. What is a video annotation tool? 6. What is a text annotation tool?
Optical metrology is a measurement technique that uses light to gather data about the physical properties of objects. This can include measurements of distance, shape, size, surface roughness, and more. Optical metrology has a wide range of applications across various fields, from manufacturing and ...
To calculate the power loss, OPM is first connected directly to an optical transmission device through a fiber pigtail, and the signal power is measured. Then the measurements are taken through OPM at the remote end of the fiber cable. The difference between the two measurements displays the to...
In more advanced use cases, AI-assisted labeling tools based on optical flow, video object tracking, or segmentation are becoming more essential to speed up annotation. SuperAnnotate's video annotation platform is made to speed up the annotation of all these use cases. Additionally, we created ...
Trapped ion qubits:Trapped ion particles can also be used as qubits and are noted for long coherence times and high-fidelity measurements. Quantum dots:Quantum dots are small semiconductors that capture a single electron and use it as a qubit, offering promising potential for scalability and compat...
Using a biometric scanner to access your devices or apps is convenient and usually very secure. But to make sure you remain protected, multi-layered security is the best approach. Two-factor authentication Two-factor authentication (2FA) means that alongside your biometric measurements another credent...
