Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...

The fragility and laws of quantum physics generally make the characterisation of quantum systems time-consuming. Furthermore, when a quantum system is measured, it is destroyed in the process. A ...

Researchers have developed new optical tweezers that can stably trap particles that are large—about 0.1 mm—and irregularly shaped. While conventional optical tweezers use highly focused laser beams to ...

Optical percutaneous needle biopsy techniques are revolutionizing tumor diagnostics, enabling real-time analysis and improving the accuracy of tissue sampling.
