Electronic shutter
The TM-1402 has a substrate drain-type shutter mechanism which provides superb pictures at various speeds
without smearing. A built-in manual shutter speed control selects the electronic shutter rate of 1/60 (non-
async mode only), 1/125, 1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/8,000, or 1/16,000 second.
With VINIT high (5V), the CCD keeps discharging. With a negative pulse to VINIT, the camera resets and purges
the charge momentarily. Then it starts integrating for the period of shutter control set by either an external
pulse width or internal shutter control. Progressive scanning permits a full 1040 lines of vertical resolution, as
compared to a conventional CCD camera which captures only half the vertical lines per shutter.
•
Asynchronous reset (VINIT)
The TM-1402's asynchronous reset is flexible and accepts external horizontal drive (HD) for phase locking.
When the VINIT pulse is applied, it resets the camera's scanning and purging of the CCD. There are 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 control mode. The speed control varies from 1/125 to 1/16,000 sec. The video signal
starts with internal V reset timing related to shutter speed.
•
Output
The TM-1402 has an 8-bit RS-644 (LVDS) digital output for interfacing with external image processing systems.
The TM-1402 camera is also available with RS-422 digital output as an option (OP-93). The TM-1402CL has a
Camera Link output. The analog output is 1.0 Vp-p composite video (75 Ω).
•
Asynchronous image capturing
The TM-1402 captures async reset images and provides single-shot video output with single FDV.This makes it
simpler for an ordinary frame grabber to capture the async reset images.
•
Warranty
The CCD solid-state image sensor allows the camera to maintain a superior performance level indefinitely while
requiring virtually no maintenance. Please contact your factory representative for details about the warranty.
Warning: Unscrewing the camera cover or opening the camera in any way will void the
warranty unless prior written approval is obtained from the factory.
