Tichawa sensors vs. conventional CIS

What is the difference between Tichawa CIS technology and conventional CIS technology?

Tichawa sensors have many new features. These include gapless sensor technology, longer working distance, inspection of round objects, vacuum capability, support for Shape From Shading technology,… and more.

Gapless inspection: A long sensor line (up to 4m) requires many sensor chips to be lined up during production. If they are lined up next to each other, gaps occur at the chip boundaries, which also affect the camera image in the form of missing pixels. Our sensor chips are arranged in such a way that no mechanical gaps occur between the sensor chips. This gives you an image without gaps.

Inspection of 3D objects with a height of up to 16mm: Conventional CIS technologies offer only a very small depth of field and a very small working distance. Tichawa Vision’s VDCIS technology offers up to 60mm working distance with a depth of field of 16mm.

Inspection in a vacuum: Conventional CIS but also industrial cameras are not suitable for use in a vacuum, as it would immediately tear the housing. Tichawa Vision offers CIS with vacuum-suitable housings that can resist pressure up to 3 bar.

Shape from Shading: Until now, the inspection of 3D structures has only been possible with complex camera and illumination systems. The technology has been known since the 1970s, is called “Shape From Shading” and works with four illumination units and one or more cameras. Tichawa Vision has combined this technology in one product and offers the Shape From Shading as CIS as a compact solution.

Inspection of round objects in the production process: Tichawa Vision has improved the CIS so that it can also be used to scan round objects such as pipes, tubes, cans, endless wires and ropes. For this purpose, our proven CIS has been bent into a “ring” through which the object is passed. In this way, the CIS was adapted to the requirements of inspecting round objects. (RingCIS)

100% Inside Inspection: For distortion-free inspection of the inside of a tube, there has been no solution on the market until now. Tichawa Vision has developed two products that make this possible: BoroCIS and the TubeCIS.

100,000 pixels/line: Tichawa products can process more than 100,000 pixels per line, allowing you to achieve high resolutions even with large scan widths.

Generation of overlaps: In the past, many image processing systems worked with multiple cameras for large scan widths. The cameras were adjusted so that the images were overlapping. The overlap was then cut out in the software. To avoid having to change the existing software, Tichawa’s CIS can simulate these overlaps.
