X-ray non-destructive inspection, etc. ApplicationsFeatures The S11299 series is a back-illuminated type 16-element photodiode array speci fi cally designed for non-destructive X-ray inspection. It has improved sensitivity uniformity and smaller photodiode element variations compared to our previous prod- uct (S5668 series). The back-illuminated photodiode array is also simple to handle and easily couples to scintillators without having to worry about wire damage because there are no bonding wires and photosensitive areas on the back side. The S11299 series is compatible with dual energy imaging because it can be used in combination with our S11212 series [board size: 25.4 (W) × 20.0 (H) mm] to con fi gure an upper and lower two layer structure capable of simultaneous detection of high and low X-rays.

This structure uses no fragile easily-broken bondin g wires since the photodiode array output terminals are directly connected by bump bonding to the electrodes on the board. This structure is robust since the board wiring is laid out within the board. The photodiode surface for coupling the scintillator has no bonding wires or photose nsitive areas, so there is less risk of damaging the photodiode array. The S11299 series is also resistant to effects from temperature cycle and so ensures high reliability. 100 105 110 1 2 3 4 5 6 7 8 9 1 01 11 21 31 41 51 6 Element no. Relative sensitivity (%) S11299 series Previous product (Typ. Ta=25 °C) The S11299 series supports dual energy imaging. To simultaneously detect high energy X-rays and low energy X-rays, the S11299 series is designed so that two photodiode arrays, each with a different scintillator, are combined in an upper and lower two-layer format. Arranging two or more S11299 series photodiode arrays in a row in close proximity also forms a line sensor that allows measurement of long objects. Our unique sensor design minimizes variations in sensitivity between photodiode elements as well as at the sensor ends. The S11299 se- ries offers signi fi cantly improved sensitivity uniformity compared to our previous product (S5668 series) and so provides optimal X-ray images.

Combination examples (for dual energy imaging) Dual energy imaging is a technique that acquires and superimposes two types of data in a single scan by using X-rays at two dif ferent energy levels (high energy and low energy). Two photodiode arrays with scintillators are used: one at the upper stage and the other at the lower stage. The upper stage is used for low energy detection, and the lower stage for high energy detection. Arranging two or more of these devices in a row also forms a line sensor for dual energy imaging. This combination uses the S11212 series in both upper and lower stages.
