RadEye Large-Area Image Sensors |
The RadEye1
large-area image sensor is a three-side buttable, fully integrated
CMOS photodiode array designed for both visible and radiation
imaging. The large 24.6 mm by 49.2 mm active area consists of a 512
by 1024 matrix of silicon photodiodes on 48 µm centers. Used
directly to detect visible light, or with a scintillator to detect
x-rays and other energetic radiation, the RadEye1 is the perfect
solution for applications ranging from medical diagnostics to
industrial inspection (NDT) and scientific imaging.
The RadEye image sensors are
fully integrated with control logic and readout circuitry that allow
the sensors to run off a single 5 V power supply and a master clock.
An optional frame start input can be used to control the frame rate
externally between 0.01 and 4.5 frames per second. An asynchronous
array reset, a high-speed binning mode, and a non-destructive
readout mode further add to the flexibility of these devices. Video
data is read out sequentially through a high-speed differential
analog output at up to 2.5 MHz. |
