Hardware Introduction
TM-1405GE Hardware
6.2 Features
The TM-1405GE has the following features:
• Miniature size and light weight
The printed circuit boards in the TM-1405GE 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 50.8mm x 50.8mm x 83.5mm in dimensions, and weighs only
212 grams.
• Imager
The TM-1405GE uses a progressive scan interline transfer CCD that has the following features:
- Resolution of 1392 x 1040 active pixels for excellent image quality.
- 4.65 x 4.65 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 at fast scanning. The CCD has an excellent S/N ratio at the
default setting greater than 51dB.
• Electronic shutter
The TM-1405GE has a substrate drain-type shutter mechanism which provides superb pictures at
various speeds without smearing. For more information, refer to Section 8.3, “Electronic Shutter,”
on page 41.
• Asynchronous reset
The TM-1405GE captures asynchronous reset images and provides single-shot video output with
single FDV. This makes it simpler for an ordinary frame grabber to capture the asynchronous reset
images. The TM-1405GE’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-1405GE has three modes to control the asynchronous reset and shutter speed:
- Async, no shutter. The video signal and FDV are reset by external VINIT.
- Async direct shutter. The shutter speed control depends on the number of horizontal lines
controlled through the serial commands.
- External VINIT with pulse width. The duration between pulse edges controls the shutter
speed externally.
• Output
The TM-1405GE has a 10-bit/8-bit Gigabit Ethernet output. The analog output is
714 mVp-p composite video (75 ohms) on all models.
