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. CAMELIA 1.6M CAMERA

2.1 CCD

♦ image format : 30.0mm(V) x 20.0mm(H)
♦ 1536(V) x 1024(H) active pixels
♦ readout register along the small side of the image area. (vertical image)
♦ pixel geometries :

◊ 19.5um(V) x 19.5um(H).
◊ aperture ratio : 100%.

♦ anti-blooming by clocking.

2.2 TIMING

3 timing modes are available :

♦ 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

♦ 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.

♦ operation with "integration time control" : integration is fully controlled by the user from the external signal ITC :

◊ the falling edge of ITC activates the start of the frame integration. This falling edge is synchronized by the

camera with a precision of 62µs

◊ the rising edge of ITC activates the stop of the frame integration. This rising edge is synchronized by the

camera with a precision of 62µs

◊ note : ITC signal period must be greater than integration time (defined by ITC low) plus frame readout

time.

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

Data rate is :

♦ pixel clock : 20 MHz
♦ frame readout time :

◊ normal mode : 100ms
◊ 2x2 pixel binning : 55ms.
◊ 4x4 pixel binning : 35ms.
