Unit III

Electronic imaging and photo detection is a key component of many complex instrumentation. In this unit we will cover some of the building blocks of important tools. We are not done building this unit, but here are some of the topics we will cover, some pages already have videos and information:

Phototubes

Semiconductor-based image technology:

Photodiodes
CCDs
The Active Pixel Sensor
Optical Spectrometers
Test Equipment with Optical Sensors
