Introduction to the
High Performance TDI Line Scan Camera
1.1 Camera Highlights
Description
The Osprey TDI camera series is an ultra-sensitive camera design for use in line scan
applications that demand high performance under low light conditions. This series of
cameras is based upon Fairchild’s CCD525 array, which is used in the very successful U.S.
Postal Service Wide Field of View (WFOV) Camera. The 2K camera versions have 2048
pixels in the cross-scan direction, with selectable TDI stages up to 96 rows. The 4K
varieties have 4096 pixels in the cross-scan direction, also with selectable TDI stages up to
96 rows. The 2K Osprey supports scan rates up to 46K lines per second while the 4K
yields up to 23K lines per second. Both the 2K and 4K styles have LVDS outputs. The
LVDS output supports 4-port, 8-bit synchronous data. This camera also includes
sophisticated features such as anti-blooming, programmable gain and offset. It is packaged
in a very compact and rugged housing that contains a standard M58 x 0.75 base lens
thread. Optional (Nikon-F) lens adapter is available.
2K x 96 TDI Sensor Architecture
• Uses time delay and integration sensor architecture
• User selectable TDI lengths of 96, 64, 48, 32
• Line rate up to 46K lines per sec
• 1000X antiblooming
• Non volatile gain/offset value memory
• <1 LSB Noise RMS
4K x 96 TDI Sensor Architecture
• Uses time delay and integration sensor architecture
• User selectable TDI lengths of 96, 64, 32, 16
• 25MHz pixel clock
• Non volatile gain/offset value memory
• <1 LSB Noise RMS

Notes:
DN = Digital Numbers, also known as “levels” (0 – 255 for 8-bit systems, 0 – 4095 for 12-bit
systems).
All measurements taken with camera operating in 96 stage mode.
All measurements exclude the last pixel of OS 1 and the first pixel of OS4.
Tested using volpi (18111.001) linght line source, default camera gain.
1. Measured across 1 tap (512 pixels – 2K) (1024 pixels – 4K).
2. Typical offset @ 20°C ambient.
3. Excludes last pixel of OS1 and first pixel.
4. Measured across all taps.
5. Measured on each tap relative to next ten pixels. Measured at Vsat.
6. Measured with digital outputs, (terminated in 100 ohms).
7. A delta window of 8 pixels is examined and shifted by half its window. First and last
pixel excluded from each tap.
8. Camera will operate below min. line rate with degraded performance.
9. Power supply must support >850 mA surge current.
1.3 Image Sensor
The family of Osprey cameras use the following Fairchild sensors: The 2K x 96 TDI
camera uses the CCD525 sensor, and the 4K x 96 TDI camera uses the CCD545 sensor.
Both sensors have 13µm square pixels on a 13µm pitch.
Both sensors are approximately 96 times more sensitive compared to line scan cameras.

1.8 Thermal Considerations
The Osprey camera series has been thermally designed to separate the camera electronics
from the image sensor.
The sensor temperature is thermally linked near the four M4 mounting holes on the face of
the camera. Fairchild Imaging recommends mounting the camera using these holes to
minimize sensor dark current artifacts.
Fairchild Imaging recommends that gain or offset corrections are completed after the
camera has been turned on for at least 15 minutes. To do offset correction, cover the lens
with your lens cap Follow this by removing the lens cap to complete a gain calibration.
Make sure that gain calibration is completed with a uniform light source, illuminating the
camera Field-Of-View (FOV).
Avoid excess ambient temperatures around the camera.
