photodiode arrays

A photodiode array is a group of small light sensors arranged in a grid, used to detect and measure light across multiple points simultaneously. Each tiny sensor, called a photodiode, converts incoming light into an electrical signal. These arrays are commonly used in imaging devices like scanners, cameras, and spectrometers, enabling high-speed, detailed analysis of light patterns. By capturing multiple data points at once, photodiode arrays allow for efficient, precise measurement of light properties across a wide area, making them essential for applications requiring rapid and accurate optical sensing.
