The S8658-01 is a front-illuminated FFT-CCD image sensor for X-ray imaging, consisting of three aligned chips forming a 220 mm long, 6.144 mm wide photosensitive area. Each chip has 1536 × 128 pixels at 48 × 48 μm, with 100% fill factor and TDI operation for motion imaging. It is housed in a 60-pin ceramic package and operates non-cooled. The sensor achieves 4 to 6 Lp/mm X-ray resolution at 60 kVp and 20 μGy, with a full well capacity of 600-1200 ke− per pixel and dynamic range of 5000-20000. Dark current is 8-24 ke−/pixel/s at 25 °C, and power dissipation is 60 mW per chip. Output and reset clock frequencies range from 2 to 4 MHz, and maximum X-ray dose is 50 Gy. Operating temperature is 0 to 40 °C.
Image sensor with a long, narrow photosensitive area for X-ray imaging (FOP type)
The S8658-01 is a FFT-CCD area image sensor specifically developed for X-ray imaging. Since a FOS (Fiber Optic plate with Scintillator) to convert Xrays into visible light is mounted on the CCD chip, X-ray images can be captured in fine detail. Three CCD chips are linearly arranged in close proximity to form a long and narrow sensor format. Effective size of each active area is 73.728 (H) × 6.144 (V) mm2, so the overall active area length of the three chips is up to 220 mm in length. Each CCD chip has 1536 × 128 pixels and the pixel size is 48 × 48 μm. When used in TDI operation mode which is a special feature of this CCD image sensor, even X-ray images of a moving object can be clearly acquired, making S8658-01 ideal for non-destructive inspection of products carried on a belt conveyor, etc.
