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 a CameraLink CameraLink include sophisticated features such as anti-blooming, programmable gain and offset. They are 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.

Notes:
DN = Digital Numbers, also known as “levels” (0 – 255 for 8-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
1. Measured across 1 tap (512 pixels) or (1024 pixels)
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.
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.

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 with 100% fill factor.
Both the CCD525 and CCD545 sensors have been designed with improved blue response. Both sensors are much more sensitive than single line CCDs used in line scan cameras.
