This article compares Frequency Modulated Continuous Wave (FMCW) and Time of Flight (ToF) for LiDAR. In summary, FMCW is better in longer term but ToF is still better now. What are FMCW and ToF? Lidar can take on several different modalities, which can be classified by their dependence on incoherence or coherence of the laser…

A new survey from Consumer Intelligence Research Partners (CIRP) has found that the average selling price (ASP) of Apple iPhones has hit an all time high of USD988 as of Mar 2023. Along with iPhone 14 Pro and Pro being the most popular models for 2023 which of course was…

Apple is reportedly preparing to unveil its AR/VR “mixed” reality headset at in Jun 2023, and the company is working to create appealing app experiences to encourage people to adopt the device. Apple is planning to adapt iPad apps for the headset, and users will be able to access existing…

Canon’s 3.2 MP SPAD camera has received some press coverage: PetaPixel: https://petapixel.com/2023/04/03/canons-new-sensor-enables-long-range-night-vision-capabilities/ YMCinema: https://ymcinema.com/2023/04/03/canon-develops-interchangeable-lens-camera-that-sees-in-the-dark/ Abstract: We present a new generation of scalable photon counting image sensors, featuring zero read noise and 100ps temporal resolution. Newly proposed charge focusing single-photon avalanche diode (SPAD) is employed to resolve critical trade-offs in conventional SPAD pixels. A prototype 3.2 megapixel 3D-stacked backside-illuminated (BSI) image sensor with 1-inch format demonstrates the best-in-class photon detection efficiency (PDE), dark count rate (DCR) and timing jitter performance with the largest array size ever reported in avalanche photodiode (APD)-based image sensors. The proposed technology paves the way to compact and high-definition photon counting image sensors for low-light imaging and 3D time-of-flight sensing.

Apple’s next-generation iPhone 15 Pro Max is widely expected to feature a so-called “periscope lens” that would allow for up to 5–6x optical zoom. Periscope technology would be built into the Telephoto lens and allow for up to 6x zoom when shooting photos with the rear camera, without any blurriness…

Lynk & Co’s new medium-sized SUV Lynk & Co 08 official image has finally been officially released, and it is expected to be launched in 2023. The car has a 12.3” full LCD instrument panel and a 15.4” floating central control screen, providing a HUD system with a wider field…
