A device made up of several photodiodes placed in a linear pattern is referred to as a linear photodiode array, photodiode linear array, or a photodiode sensor array. When exposed to light, photodiodes, which are semiconductor devices, produce an electrical current.
A single row or column of numerous photodiodes are often arranged side by side to make up a linear photodiode array. As a unique light detector, each photodiode transforms incident light into an electric current.
A spatial profile or image of the incident light can be created by merging the outputs of all the photodiodes in the array.To gauge the strength of various light wavelengths, spectrometers employ linear photodiode arrays.
The makeup of a light source can be ascertained by sweeping the array throughout a spectrum. In order to recognise and decode the black and white bars of a barcode, barcode scanners use linear photodiode arrays.
The encoded information is extracted from the electrical signals produced by processing the photodiodes, which each correspond to a certain area of the barcode. By sensing variations in the light intensity falling on the array, linear photodiode arrays can be utilised to determine the position or motion of objects.
Applications like robotic navigation, object tracking, and gesture recognition all make use of this. Although they cannot produce high-resolution images like a camera, linear photodiode arrays can be utilised for straightforward line-scan imaging.
One-dimensional images of the item can be taken by moving the object or the array. Light metres and exposure control systems use linear photodiode arrays. They can gauge the amount of light present in various areas of a scene and offer suggestions for improving the lighting.
In conclusion, a device with many photodiodes arranged in a linear pattern is known as a linear photodiode array. Applications include imaging, light measurement and control, position sensing, barcode scanning, spectroscopy, and position sensing.
The global linear photodiode array market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The 512 and 1024 element LE/LSE InGaAs array products have pixel heights of 250 and 500 m and a pixel pitch of 25 or 50 m. 0.8 to 1.7 m in the standard wavelength range or 1.1 to 2.2 m in the extended wavelength range. By stopping charge flow from saturated pixels, anti-blooming protection increases the intra-scenic dynamic range.
This is precisely what the Waters 2998 Photodiode Array (PDA) Detector is made to accomplish in addition to enhancing your LC and LC-MS systems.
