The sensor board has 8 charge-sensitive amplifier arrays each having 78 ch amplifiers with a horizontal shift register. Analog video signals are amplified as the charge on each video line by 624 ch charge amplifiers with CDS (Correlated Double Sampling) circuits added, and are output each of 8 amplifier arrays. The control board converts the analog video signal into a 13-bit digital signal and outputs it to an external frame grabber through the 13-bit parallel port.

To acquire images through an image grabber board, write parameters in the software program or parameter file by referring to the following timing chart and description. KACCC0361EB

1 FRAME

All pulses are counted in the “High” period of Hsync+ All pulses are counted at the riging edge of Pclk+. The effective video output is only included in the “Phe” period. Hsync+ are output continuously while Vsync+ is low. LAST ROW Vsync+ (GRABBER) Vsync+ (GRABBER) Hsync+ (GRABBER) Hsync+ (GRABBER) Pclk+ (GRABBER) Parameter Count Effective line 616He Dummy line 8 Effective pixel 608Phe Dummy pixel 16 Phd 177 Pg 157 Note: “He” is the Hsync count. Phe, Phd and Pg are the Pclk count. KACCC0351EA RECOMMENDATION: 50 % OF FRAME TIME FROM Tmin TO Tmax Tvd ExtTrgLemo ExtTrgGrb (TTL) Vsync+ (LVDS) Hsync+, Pclk+ and Data 1-13 are the same as internal trigger mode.

  • Tmin is defined as 1/Sf (int).
  • Tmax is defined as the reciprocal of the minimum value of Sf (ext).
  • Tvd=96 µs I External trigger mode To acquire images in external trigger mode, input an external trigger pulse as shown below. When the time Tvd has passed after the rising edge of the external trigger pulse, synchronous signals and video signals are output.

To operate C10322D at full performance, the following system and peripherals are required.

  • PC: IBM compatible PC running on Windows XP
  • Digital frame grabber card: Monochrome 16 bits or more, pixel clock 15.15 MHz or more, LVDS interface synchronous signal (See the frame grabber manual.) The National Instruments IMAQ PCI-1424 (NI parts No. 777662-02) frame grabber has been verified to successfully acquire 13- bit digital images from C10322D. The IMAQ PCI-1422 (NI parts No. 777959-02) also acquires satisfactory images from C10322D. You can utilize the demonstration software that comes with the frame grabber as a simple viewer, to acquire and save an image. To do so, refer to the frame grabber user’s guide for how to use the camera information file for the demonstration software. Please use a low noise series power supply. (Avoid using a switching power supply.) A power cable and a frame grabber cable do not come supplied with C10322D. The voltages described above are specified at the flat panel sensor side. Install a noise filter on the AC power input line to prevent surges on the AC line. The earth terminal must be connected to a stable earth point to eliminate noise from surround- ings.
  • No piece of acquisition software nor image processing library is attached to the sensor.
