Synchrotron is a particle accelerator that accelerates electrons to light speed, emitting a continuous spectrum of light with high intensity, broad spectral range, narrow collimation, high polarization, and pulsed time structure.

Satellite communication uses artificial satellites for various applications, offering advantages like easy installation, elasticity, and coverage, but also facing initial expenditure, frequency blockage, propagation, and interference.

AFM is a scientific instrument for observing and manipulating nanoscale matter, enabling high-resolution visualization and individual atom and molecule properties measurements.

Radar is a technology that uses radio waves to detect, locate, and track nearby objects. It uses electromagnetic energy to reflect and reradiate waves, indicating obstacles in propagation.

MRI is a medical imaging technique that captures images of internal body structures. It is safe for soft tissues but potentially affects objects.

"Gravimeter" is a sensitive device that measures the gravitational field of the Earth at a certain spot.

Tachometers measure rotating object speed using electromagnetic induction theory, essential in industries for driver adjustments, gear changes, and engine protection.

Luminometer detects visible light emission using photomultiplier tubes, converting them into pulses or analog current. Hygiena luminometers detect residual ATP for surface cleanliness.

Multimeter, types, uses

Laser Doppler vibrometry measures motion and velocity in fields like science, engineering, and acoustics using high resolution and linear amplitude.
