The Cohu board-level CCD camera has been designed to fit the needs of OEM customers who require high performance video in a compact package. The 1100 Series features a resolution of 580 HTVL (RS-170) or 560 HTVL (CCIR) with a matrix of 768 (H) x 494 (V) active pixels, internal crystal or external synchronization, and 2 to 16 field/8 step integration or shuttering to 1/10,000 sec.

Configuring the 1100 Series for custom purposes is quite easy. A flexible cable allows for virtually any orientation of the sensor with respect to the control board. Measuring less than 2" x 4", this feature/size combination is ideal for machine vision and image processing applications.

The 1100 Series cameras feature a 1/2" or 1/3"-format on-chip microlens sensor, which improves sensitivity and provides increased dynamic range while reducing lag, blooming and dark current. For video applications prone to streaking problems, a 1000:1 overload capability allows transmission of clear video signals even when bright incidental light is present in the scene.

Both RS-170 and CCIR cameras have 20 dB of AGC for high sensitivity in low light-level applications.

This single board camera synchronizes from an internal crystal, or external horizontal/vertical source.

Asynchronous reset accepts an external trigger input to reset the camera to the beginning of the vertical interval (field 1, line 1). The first field of video information reads out 9.5 horizontal lines after triggering.

Four modes of operation can be selected: field (interlace and noninterlace), and frame (interlace and noninterlace). The integration time in the field mode is 16.6 mS for each field.

Interlace mode sums two rows of pixels from each line, thus increasing the sensitivity. The non-interlace mode uses only field one, or one-half (242) the number of vertical pixels. The advantage of non-interlaced is using the same field of pixels every 1/60 second for repeatability. The integration time of each field in the frame (interlace) mode is 33.3 mS, for a vertical resolution of 485 pixels. Operating in the frame interlace mode and strobing will achieve full frame resolution of fast moving objects.
