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:
CPU: TI OMAP4430
RAM: 682 MB
Display resolution: 640 x 360 pixel (very important information)
Internal storage: 16 GByte
Sensors:
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 ……
Figure 1 cracking open Glass from Bill Detwiler and TechRepublic. I think (a) the flexible PCB with white characters is the interconnection between these module; (b) the small connector near the prism is connected to RGB LED light source.
