Truesense Imaging has released three image sensors suitable for intelligent traffic, machine vision, security, and other applied imaging applications. The sensors are the 12 megapixel KAC-12040 CMOS sensor, the 1080p KAI-02170 interline CCD sensor, and the 4 megapixel KAI-04070 interline CCD sensor.

The 12 megapixel (4,000 x 3,000) KAC-12040 sensor is the first in a planned family of CMOS devices. They combine high image quality under both global and rolling shutter operation with very high frame rate, flexible readout modes for accessing multiple regions of interest, and excellent near-IR sensitivity. Based on a 4.7µm pixel architecture, the 4/3 optical format KAC-12040 supports multiple regions of interest (ROI) and interspersed video streams, making this device ideal for applications requiring both high resolution and high frame rates.

The KAI-02170 and KAI-04070 sensors are the latest members of the Truesense 7.4µm interline transfer CCD family. The KAI-02170 is an upgrade to the existing KAI-2093 sensor, retaining the 1080p (1,920 x 1,080) resolution in 1-inch optical format of the older device, but providing faster frame rate (up to 60fps) and improved image quality. In similar manner, the KAI-04070 improves upon the existing KAI-4011, KAI-4021, and KAI-04022 family of products by retaining the same 4 megapixel (2,048 x 2,048) resolution in a 4/3 optical format, but again providing increased frame rate (up to 28fps) and improved image quality.

Dynamic range of the new devices is 70dB, and can be extended to 82dB in binned pixel operation. They provide -115dB of smear rejection. The new devices are also pin and package compatible with Truesense Imaging’s 5.5µm pixel family of products, allowing camera manufacturers to use existing camera designs to support the new devices.

The sensors are supplied in monochrome and Bayer colour configurations.
