Ultra-High Performance Line Scan Camera

1.1Camera Highlights

Description

The OWL CMOS Line Scan Camera is an ultra-sensitive camera for use in line scan applications that demand high performance under low light conditions. The camera is based upon a 2K CMOS linear sensor that utilizes an active reset technology to obtain high performance in low light applications while operating at very high data rates. Two versions of this camera are available.

RDI (Read During Integration) mode runs at line rates up to 38 KHz. Read noise for this version is ~9e- (<5.7DN in 12 bit data).

MRDI (Multiple Read During Integrate) mode has a maximum read noise of 0.4e- at a maximum line rate of 2.9KHz.

The CMOS linear sensor that is used in this camera has a unique feature that allows gain selectability at the pixel level. The gain of each pixel can be switched between high or low gain. In the high gain mode, the noise is minimized, while in the low gain mode, the dynamic range is maximized.

The 12-bit output of this camera line utilizes CameraLink and will provide data at 80 MHz (40 MHz per output). The camera offers features such as anti-blooming and programmable gain and offset.

It is packaged in a very compacted and rugged housing that contains a standard M58 x 0.75 base lens thread. Optional (Nikon F or C Mount) lens adapters are available.

Programmability

•Simple menu-based configuration for selection of gain, calibration, test patterns operational control, and diagnostics.

•CameraLink TM camera-PC communications.

Usability

•Programmable gain, offsets, and controls

•Internal flat field correction

•Easy integration “plug compatible” Camera LinkTM interface

•Exposure control
