JAI TM/TMC-4200CL Manuale Utente

Applications for the TM-4200CL include machine vision, medical imaging, intelligent transportation 
systems, high-definition graphics, on-line inspection, gauging, character reading, archiving, and high-
security surveillance.

The printed circuit boards in the TM-4200CL have been arranged based on a new design 

philosophy. This creates modular electronics for the camera, giving it flexibility. In addition, the 
use of miniature solid-state components results in a compact, lightweight camera that is 51mm x 
518mm x 74mm in dimensions, and weighs only 152 grams. 

The TM-4200CL uses a dual-tap progressive-scan interline transfer CCD that has the following 

features:

Resolution of 2048 x 2048 active pixels for excellent image quality.

7.4 x 7.4 µm square pixels for precise dimensional measurement.

High-speed electronic shutter capability, that eliminates the need for a mechanical shutter 

through high dynamic resolution of moving objects .

Progressive-scan CCD eliminates interlace deterioration of image and increases ease of 

computer interface.

High sensitivity and low noise with fast scanning rates. The CCD has an excellent S/N ratio 

that is greater than 54dB.

The CCD has built-in microlens technology for increased quantum efficiency.

The TM-4200CL has a substrate drain-type shutter mechanism which provides superb pictures at 

various speeds without smearing. For more information, see Section 6.4, “Electronic Shutter,” on 
page 38.

The TM-4200CL captures async reset images and provides single-shot video output with single 

FDV (frame data valid). This makes it simpler for an ordinary frame grabber to capture the async 
reset images. The TM-4200CL’s asynchronous reset is flexible and accepts external horizontal 
drive (HD) for phase locking. When the VINIT (5V) pulse is applied to CC1, it resets the camera's 
scanning and purging of the CCD. 

The TM-4200CL has two modes to control the asynchronous reset and shutter speed:

External VINIT with pulse width. The duration between pulse edges controls the shutter 

speed externally.

Internal shutter speed control. The speed control varies from 1/125 to 1/16,000 sec. The 

video signal and FDV starts with internal V reset timing originally set to respond to shutter 
speed, although this can be changed to sensor or other input.
