Line Sensors

CMOS linear image sensors are now widely used in industrial measurement applications. This is as a result of the innovations in CMOS technology, which have increased integrated circuit density, allowing all essential signal-processing circuits to be formed on the sensor chip. This has made CMOS linear image sensors easier to use and available at a reasonable cost.

Photodiode arrays with amplifiers are a type of CMOS image sensor designed mainly for long-area detection systems using an equal-magnification optical system. This sensor has two chips consisting of a photodiode array chip for light detection and a CMOS chip for signal processing and readout. A long, narrow image sensor can be configured by arranging multiple arrays in a row. For non-destructive inspection, Hamamatsu offers Photodiode arrays with an amplifier and GOS scintillator strip attached to the active area. These products are designed for non-destructive inspection with a detectable energy range from 30 keV to 100 keV.

Hamamatsu’s Photodiode arrays can be used for medical, food and security applications.

Photodiode Arrays: Silicon photodiode arrays consist of a number of single element photodiodes of the same size, forming a line sensor. They can be coupled to various types of scintillators, such as plastic, ceramic and CsI depending on the specific application.

Photodiode Arrays are particularly useful for mail and parcel screening applications as well as in simple baggage inspection systems.
