1. IMAGING SYSTEM DESCRIPTION

♦ CAMELIA camera is powered by a +24V power supply.
♦ CAMELIA camera is configured through the serial port of the computer.
♦ CAMELIA camera sends digital video to the FGT frame grabber.
♦ As CAMELIA 's CCD is a full frame sensor, you must use either pulsed lightning or a chopper/shutter in front of

the camera in order to have incident lightning on the CCD only during integration time. You must design an
electro-optical interface to drive camera, shutter/chopper or lightning by using the "SHUTTER" signal delivered
by the camera. If required, the system can send an external trigger or external ITC (integration time control
signal) to the camera.

2. CCD DESCRIPTION

♦ image format : 35.0mm(V) x 23.0mm(H)
♦ active pixels :

Mode (set via RS232) Image size (H x V)

No binning 2300 x 3500
2x2 pixel binning 1150 x 1750
4x4 pixel binning 574 x 875

♦ readout register along the small side of the image area. (vertical image)
♦ pixel geometry :

◊ 10µm(V) x 10µm(H).
◊ aperture ratio : 100%.

♦ filter mosaic : BAYER pattern :

B G B G
G R G R
B G B G
G R G R

◊ note : first active pixel of first active line : blue.

♦ anti-blooming by clocking.

3. TIMING

2x2 and 4x4 pixel binning are possible to enable previewing modes.

3.1 FRAME TIMING

♦ frame readout time :

◊ normal mode : 370ms
◊ 2x2 pixel binning : 200ms.
◊ 4x4 pixel binning : 110ms.

3 timing modes are available.

3.1.1 CONTINUOUS

♦ the camera delivers frames continuously :

◊ frame N+1 integration starts as soon as frame N readout is completed.
◊ integration time is set by RS232

3.1.2 OPERATION WITH EXTERNAL TRIGGER

♦ integration start is controlled by the user from the external signal TRIG :

◊ The rising edge of TRIG activates the start of the frame integration. This rising edge is synchronized by

the camera with a precision of 62µs

◊ Integration time is set by RS232
◊ Note : TRIG signal period must be greater than integration time plus frame readout time.
