1 Hardware Introduction
1.1 Product Description
The JAI Inc. TM-2040GE series
1
is a Gigabit Ethernet output, high-resolution progressive scan CCD camera. The
interline-type CCD permits full vertical and horizontal resolution of very high speed shutter images and
applications. The electronic shutter, which has speeds to 1/32,000 sec., can be reset asynchronously by
external pulse control. The frame rate for a full image is 34 fps. A square imager format with uniform square
pixels provides superior image definition in any orientation. On-chip micro lenses provide increased sensitivity.
12-bit internal processing can be converted to 8-bit, 10-bit, or 12-bit output.
The TM-2040GE has a full dynamic range control function, which can be set at externally selectable look-up
table (LUT) knee slopes thereby optimizing the CCD’s full dynamic range in the normal output signal range. As a
Gigabit Ethernet output camera, the TM-2040GE has semi-auto-gain balancing functions. The camera does not
have a LUT for the 12-bit output.
Applications for the TM-2040GE include machine vision, medical imaging, intelligent transportation systems,
high-definition graphics, on-line inspection, gauging, character reading, archiving, and high security
surveillance.
1.2 Features
•
Small size and light weight
The printed circuit boards in the TM-2040GE have been arranged to create modular electronics, giving the
camera flexibility. In addition, the use of miniature solid-state components results in a compact,
lightweight camera that is 51mm x 51mm x 85mm in dimensions, and weighs only 216 grams (7.6 oz.).
•
Imager
The TM-2040GE uses a dual-tap progressive scan interline transfer CCD that has the following features:
− Resolution of 1600 x 1200 active pixels for excellent image quality.
−
7.4 x 7.4 µm square pixels for precise dimensional measurement.
−
High-speed electronic shutter capability for high dynamic resolution of moving objects
that eliminates the need for a mechanical shutter.
−
Progressive scan CCD eliminates interlace deterioration of image and increases ease of
computer interface.
−
High sensitivity and low noise during fast scanning. The CCD has an excellent S/N ratio at
the default setting that is greater than 58dB.
−
The CCD has built-in micro-lenses for increased quantum efficiency.
