Core Technologies Of Physics Experimental Instruments

For physics experimental instrumentation-particularly sensor-based devices-core components typically include: for resistance strain gauge sensors, a DC regulated power supply, metal foil strain gauges, differential amplifiers, and digital voltmeters; and for fiber-optic sensors, lasers, power meters, fiber cleavers, and five-axis adjustment stages.

Key technologies encompass the critical operations performed during experimental procedures, such as the precise alignment of optical paths via five-axis adjustment stages; the management of environmental parameters-specifically temperature control-using digital display regulators; and the detection and processing of signals utilizing digital voltmeters, power meters, and display units.
