Product Description

This camera features an outstanding sensitivity and SNR, even at maximal speeds.

The ROI allows to increase the frame rate (for instance, 175 fps in VGA format 1M60).

ATMOS™ cameras are based on a rolling shutter CMOS sensor.

The configuration interface provides access to advanced functions (contrast expan-

sion, image calibration, LUT). The versatile and compact mechanical housing enables

you to implement various configurations.

These features combined with a compelling price, make ATMOS

an attractive alterna-

tive for users of megapixel cameras.

Applications

High-speed, SNR performance and reliability of this camera make it suitable for

machine vision, especially:

•

Material Inspection (e.g. glass, IC, PCB)

• Robot Guidance

• Metrology

and various applications like:

•

Microscopy

• Surveillance Demanding Tasks

4. Timing 4.1 Synchronization Modes The camera operates in rolling shutter mode. 4.1.1 Optimal Use of the Rolling Shutter As shown in the following timing diagrams, Figure 4-1, exposure does not happen at the same time for all lines, which can lead to image distortion when capturing fast moving objects.
PAGE 7
[Preliminary] ATMOS -1M60/1M30 If shutter time is set to > 0: Readout is suspended between two consecutive frame readout and shutter output signal is activated (programmable polarity) for a time configurable within 0 to Tsh range by step of T1. Table 4-1. Label Shutter Time Values at Free-run Mode Description 1M60 1M30 Tsh Maximum shutter time (ms) 655 1310 T1 Step duration (µs) 10 20 Figure 4-2.
PAGE 8
The trigger delay is a few µs. The minimum pulse duration is 1µs. The edge of trigger is programmable. The source of trigger is selectable between CameraLink CC1 signal and TTL/IO trigger input. The period is defined by readout time + programmable shutter time + readout time + wait. Therefore the minimum period is 2 × readout time. See register Aperture Shutter Time @ 246H, Internal Register Mapping on page 17. Table 4-2.
PAGE 9
[Preliminary] ATMOS -1M60/1M30 Therefore the minimum period is reduced to 1 × readout time. As the integration time is not the same for all lines (in the following timing diagram line n integration time is greater than line 1 integration time) this mode must be used with a pulsed light source or a shutter element. Moreover any residual light when shutter output signal is inhibited must be avoided. The exposure time is defined by the shutter time and all the lines are exposed during the same time.
PAGE 10
• Readout of dummy frames (to prevent against large dark current integration) while the camera waits for the next trigger event The integration delay is a few µs. The minimum pulse duration is 1µs. The source of ITC signal is selectable between CameraLink CC1 signal and TTL_IO trigger input. See Register Mode Control @ 204H Internal Register Mappingon on page 17 The period is defined by the ITC signal period.

5. Camera Features 5.1 Region of Interest The full resolution of the camera is 1312 pixels by 1024 lines.You might program a smaller resolution in order to reduce the readout time. You must be careful that depending on the sequencing mode, the exposure time can be reduced too.The authorized values for horizontal size are 32 to 1312 pixels. This value is rounded to the lower multiple of 16 pixels. The authorized values for vertical size are 32 to 1024 lines.

[Preliminary] ATMOS -1M60/1M30 1. The pixel depth is set by default at 12-bit, it can be set to 10 or 8-bit. The assignment for each configuration comply with the specifications of the CameraLink interface standard. See register Mode Control bits [3:2] @ 204H, Internal Register Mapping page 17 . 2. In standard mode the camera provides output data on a single channel of the CameraLink output interface. You might program the camera in two outputs mode, only with the 1M60.
PAGE 14
5.7 Look- up Table (LUT) The look-up Table is a conversion table which applies to the sensor data. At each input pixel value corresponds a single output value. This allows you to apply a correction table like a gamma correction for example. The Look-up Table might be generated by the camera by programming the gamma setting: • Gamma 0.125 to 7.875: code 1 to 63 (0 not admitted) You might also write your own correction table via the serial communication channel.
