“ SPAD”（单光子雪崩二极管）：
宣布已开发出世界上第一个图像传感器，该传感器能够在具有信号倍增像素结构的传感器中捕获100万个像素。
SPAD图像传感器：
在极短时间内发生的高速现象
用作二维照相机以拍摄特殊的静止图像和视频
它用于3D相机，该相机获取到对象的距离信息作为图像。
即使在自动驾驶中，它也有望用于测量车辆之间的距离。
高性能的“眼睛”似乎吸引了人们的注意。

Canon develops world’s first 1-megapixel SPAD image sensor
TOKYO, June 24, 2020—
Canon Inc.
announced today that the company has developed the world’s first1 single photon avalanche diode (SPAD) image sensor with signal-amplifying pixels capable of capturing 1-megapixel images.
SPAD image sensors
are ideal for such applications as 2-dimensional cameras, which capture and develop still image and video in an extremely short span of time.
These sensors also hold potential for use in 3-dimensional cameras due to their ability to obtain information about the distance between them and a subject as image data.
A SPAD sensor
is a uniquely designed image sensor in which each pixel possesses an electronic element.
When a single light particle, called a photon, reaches a pixel it is multiplied—as if creating an “avalanche”—that results in a single large electrical pulse.
The ability to generate multiple electrons from a single photon provides such advantages as greater sensitivity during image capture and high precision distance measurement.
