TM/TMC/RM/RMC-2030CL
3 Hardware Introduction
3.1 Product Description
The JAI Inc. TM/TMC/RM/RMC-2030CL series
1
is a 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 1/26,000 sec., can be reset asynchronously by external pulse control.
The frame rate for a full image is 32 fps. A square imager format with uniform square pixels provides superior
image definition in any orientation. On-chip micro lenses provide increased sensitivity to convert 12-bit input
to 10-bit or 8-bit output.
The TM-2030CL

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. The
TM-2030CL has semi-auto-gain balancing functions. The camera does not have a LUT for the 12-bit output.
Applications for the TM-2030CL include machine vision, medical imaging, intelligent transportation systems,
high-definition graphics, on-line inspection, gauging, character reading, archiving, and high-security
surveillance.
3.2 Features
•
Small size and light weight
The printed circuit boards in the TM-2030CL 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 74mm in dimensions, and weighs only 216 grams (7.6 oz.).
•
Imager
The TM-2030CL uses a dual-tap progressive scan interline transfer CCD that has the following features:
−
Resolution of 1920 x 1080 active pixels for excellent image quality.
−
7.4 x 7.4 μ m 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 57dB.
−
The CCD for the TM-2030CL has a built-in microlens for increased quantum efficiency.
Note: The Kodak KAI-2093 imager used in the TM-2030CL is packaged using a clear coverglass that does not
have anti-reflective (AR) coatings. This is because the imager is not available from the manufacturer,
Kodak, with AR coating on the coverglass.
The camera will function normally and provide high quality imaging without AR coating. However, in low
light applications that are either high magnification or wide field-of-view, reflections between the back
of the optics and the coverglass may occur. In low light conditions, portions of these reflections may
cause some visible aberrations or ghosting.

Electronic shutter
The TM-2030CL has a substrate drain-type shutter mechanism which provides superb pictures at various speeds
without smearing. For more information, please see Section 5.5 on page 28.
