An interferometer is a device used to measure various parameters of light by dividing the light into several light beams.
Most of the sensors carry out switching action through solid-state circuits. The connections between load devices and power supplies are made through two or more wires, and the entire setup is known as the electrical interface circuit.
Motion capture, which is also referred to as motion tracking, is the method of recording movements of people and objects.
A new generation of intelligent or smart sensors is fast replacing basic sensors across the spectrum of industries. An intelligent sensor comprises a sensing element, an analog interface circuit, a bus interface, and an analog-to-digital converter fitted inside a single housing.
Image sensors are instruments used for converting optical images into electronic signals. The global image sensors market has grown immensely due to technological advancements in the last decade. This has stimulated diversification in image sensor applications. Image sensors have been placed on board NASA’s Interface Region Imaging Spectrograph (IRIS) spacecraft to capture the first images of the Sun.
Ultrasonics is defined as vibrations of frequencies greater than the upper limit of the audible range for the human ear.
Laser triangulation sensors determine the position of a target by measuring the reflected light from the target surface. Based on their intended application and performance, these sensors can be classified into two categories.
MTI Instruments, a company specializing in non-contact measurement solutions, offers the Accumeasure capacitance-based systems that are specifically designed to perform noncontact measurements of runout, position, vibration, and displacement.
Nicéphore Niépce is widely attributed as being the inventor of photography, but he may not have envisioned how far camera technology would advance. Printable image sensors are one such development that has offered manufacturers huge benefits in flexibility, scalability and cost.
