combining multiple packages, is a clear step towards reducing development costs. In addition, Python [On Semiconductor’s sensor range] introduces a speed increase while reducing the region of interest in both directions. Tis is particularly important for motion analysis applications. Te frame rate scales almost linearly with the resolution, and is not limited by line timing.’ According to Diezemann, a camera


manufacturer like IDS requires one year from receiving a new sensor to the camera reaching serial production. ‘Sensor manufacturers want their sensors to be integrated in camera designs quickly and in high volumes,’ he said. ‘Sensor manufacturers are now using the same housing, the same pining, the same internal register layout for their new sensors, so it’s very easy for a camera manufacturer to change sensors. Tis means that time-to- market for new cameras is much faster than years ago.’ On Semiconductor’s Python family of image


product family where all sensors have the same data, control and optical interface. In terms of speed, machine vision CMOS sensors


are available offering up to 500fps, which means systems are able to inspect fast-moving machinery like car engines or webs of material running at high speed. A fast sensor can also give high dynamic range by combining images taken at different exposures. Machine vision sensors also oſten now have

Te entire family of sensors can be supported from a single PCB, resulting in a hardware-scalable


features like sequencer and multi-area of interest (AOI), remarked Diezemann. Multi-AOI increases the frame rate with windowing – so that, for tracking a package, for example, the engineer would set up four areas of interest to track the four corners of the package. Sequencer allows the sensor to change registers automatically from one image capture to another – the first image might be a 10ms exposure, the second


image 5ms and the third 1ms. So, with one trigger, three images are captured at different exposure times to combine them into a high dynamic range image.


Life sciences Te life sciences market always used to be dominated by CCDs because of their superior image quality. Now, according to Dr Ruediger Bader, a sales engineer at Hamamatsu Photonics UK, CCD sensors are being replaced by scientific CMOS sensors for life science imaging. Te advantages of sCMOS sensors are: high

speed in the hundreds of frames per second region without having the higher read noise typical for CCDs; larger sensor areas for a wider field of view and higher resolution; and a high dynamic range. Scientific CMOS sensors are also cost-effective compared to other low light detectors such as EMCCDs. Dr Bader explained that new sCMOS sensors


are large enough to be divided into two separate image halves, with the light from two distinct
