ActLight DPD Achieves Single-Photon Sensitivity

PRNewswire: ActLight, a Swiss technology startup developing Dynamic PhotoDiodes (DPDs), announces that the results of its internal tests performed on its most recent technology developments show a device sensitivity that reached the single photon level.

Moreover, the tests confirmed that the sensitivity of the DPD is tunable (i.e. at 2, 3, 5 or 7 photons) with very positive impact on the dynamic range of the device. Important to note is that the brilliant results were achieved at 1.5V bias voltage and with devices manufactured using a standard CMOS 180nm technology.

"It's great that today we are among a selected few innovative technologies to have a talk at the Imaging & Sensors Summit, a great opportunity to present our recent developments in the low voltage single photon sensitivity," said Serguei Okhonin, ActLight Co-Founder and CEO. "And we strongly believe that our DPDs can inspire innovation and enhance user experience in main stream applications such as smartphones and others."

In another presentation, ActLight announces a ToF sensor prototype based on its DPD (see demo video here):

"In current 3D camera sensors, pixel scaling is limited due to complex analog circuits. The DPD's simple digital front-end allows decreasing pixel size below 5 um. Moreover, the DPD and its read-out front-end circuit are implemented on the same substrate in standard low-cost CMOS technology and do not require high voltage for its operation."

Photonics Spectra on Emerging Image Sensor Applications

Photonics Spectra publishes an article " Emerging Applications Drive Image Sensor Innovations " Hank Hogan. Few quotes: " Vendors are responding by increasing sensor spectral range, integrating new capabilities into devices, and adding features such as 3D imaging. The result can be rapid growth in sensors, even in areas that are relatively stable. For instance, the worldwide market for cars is expanding at a relatively modest pace, according to Geoff Ballew, senior director of marketing in the automotive sensing division of chipmaker ON Semiconductor Corp. of Phoenix. However, tepid growth is not the case for the automotive imaging solutions. “The number of sensors consumed and attached to those cars is growing wildly,” he said. “The image sensor chip business is growing in excess of 15 to 20 percent a year. The reason for that is cameras increasingly are adding new functionality to cars.” Automotive sensors are expected to work from -40 to 125 °C. That interacts with th...

Samsung Expects 10% of Smartphones to Have Triple Camera Next Year

SeekingAlpha : Samsung reports an increase in image sensor sales in Q2 2018 and a strong forecast for both its own image sensor and also the image sensors manufactured at Samsung foundry. Regarding the triple camera trends, Samsung says: " First of all, regarding the triple camera, the triple camera offers various advantages, such as optical zoom or ultra-wide angle, also extreme low-light imaging. And that's why we're expecting more and more handsets to adopt triple cameras not only in 2018 but next year as well. But by next year, about 10% of handsets are expected to have triple cameras. And triple camera adoption will continue to grow even after that point. Given this market outlook, actually, we've already completed quite a wide range of sensor line-up that can support the key features, such as optical zoom, ultra-wide viewing angle, bokeh and video support so that we're able to supply image sensors upon demand by customers. At the same time, we will continue t...
