This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

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 ...

Scientists have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...

Traditional computers are fast, but nothing like the speed of light—at 186,000 miles per second, you can crunch numbers awfully quick. That’s a big reason why optical photonics are being used for ...

The MLX75306 is the Melexis 3rd generation automotive linear optical sensor array,including a 142 x 1 array of photodiodes, associated charge amplifier circuitry and a pixel data-hold function that ...
