ECE516 Lab06 (build a simple 1-pixel camera)
Whereas many people get lost in a sea of pixels
and therefore don't understand what a camera fundamentally senses,
we will take away all the "forest" of pixels but for one lonesome "tree"
so that you can see clearly what a camera is.
There are two parts to Lab6:
- 6a. Build a
simple one-pixel camera (link):
once you understand this, you'll understand imaging in
general, and its most fundamental question: "What is a pixel and what does
it represent, i.e., as a quantity, specifically what does the pixel
quantity represent?
- 6b. Quantifying the 1-pixel camera:
Quantimetric/Quantigraphic sensing....
Marking:
- Mechanical+optical build of the 1-pixel camera (nice box with
pinhole or lens). 2/10
- Electrical build, e.g. reading out the quantigraphic quantity, q. 2/10
- Collect quantigraphic data from your 1-pixel camera:
obtain ordered pairs (f,g). 1/10
- Plot g as a function of f. 1/10
- Plot f as a function of q. 1/10
- Determine the mathematical relationship between f and q, based on
the data for your camera. 1/10
- Repeat the above for the examples shown in class.
1 mark for repeating with the photoresistor
data gathered in a previous year's lecture
(link) and 1 mark for repeating with the
data gathered from the Blue Sky solar cell (link)
gathered in another past lecture, for both of these, 2/10.

The kinds of things I like are things that are
extremely simple yet profoundly deep conceptually.
