Flash CMOS image sensors tailored for 3D laser profiling/displacement apps

Teledyne e2v announces its Flash CMOS image sensor family, specifically tailored for 3D laser profiling/displacement applications and high speed, high-resolution inspection.

The new Flash sensors feature a 6μm CMOS global shutter pixel which effectively combines high resolution and fast frame rate. They are available in a 4k or 2k horizontal resolution, with respective frame rates of 1800fps and 1500fps (8 bits), and respective readout speeds of 61.4Gbps and 25.6Gbps (the best Gbps/price ratio in the market). The sensors come in a µPGA ceramic package fitting in standard optical formats, APS-like optics in the 4k and C-Mount in the 2k.

Designed to enable easy and cost-effective integration for camera makers, the new sensors include a wide range of application-based features including:

• High Dynamic Range modes with up to 100dB that enables both the measurement and inspection of highly-reflective surfaces and dark areas in the same image
• Multiple Region of Interest mode that provides the ideal tradeoff between profiling rate and range/resolution in the height measurement
• Frame to frame ‘hot’ changes mode of some parameters (exposure time, binning, ROI, flipping and conversion time) that enables flexibility and real-time adaptation to the environment conditions
• Different trigger modes that allow customers to adapt, depending on the speed of production lines

Flash image sensors are available with a wide range of derivatives at sensor level, so that customers can differentiate to meet specific applications challenges. Examples include, multiple operating modes which trade-off between frame rate, power consumption and the number of bits, increasing frame rate by utilizing horizontal binning and the capability to optimally fit the Scheimpflug angle required for your specific application.
