Since my major is Optical Engineering, I am very exciting about Google Glass, and also keep eyes on it from the beginning. Several months after introduced glass, the explore edition hit the developer. Some of them make a teardown test, even it was not a completely teardown, we can get lots of information from it.

This post is an original “research” article, based on teardown information that I can find in the Internet. Shows how we can get an almost complete optical layout from the information.


First, according to several hackers and developers[1][2][3][4][5], the hardware configuration is:


RAM: 682 MB

Display resolution: 640 x 360 pixel (very important information)

Internal storage: 16 GByte


Invensense MPU9150=Invensense MPU6050 (3 axis gyroscope + 3 axis accelerometer)+Asahi Kasei AKM8975 (3 axis geomagnetic sensor(compass))

LiteON LTR-506ALS rear-facing sensor(RFS) or “proximity” sensor

One more thing, glass support “wink” command, up to 20 winks!

So here is main information source from teardown test from Bill Detwiler [1] [5] <- hit it, very good articles. He opened the front shell ……
