In the spring of 2022, I created an infrared camera as a cumulative independent project for the class "Modern Electronics." I designed and built an infrared camera from the ground up, calibrating individual infrared sensors, interpreting data using solid state electronics, and displaying that data on a LED array. In just seven weeks, I was able to create a working prototype.

Phase One: Design
Phase One: Design
I worked with Ben King, the Bowdoin Machinist to design a part to mount the nine infrared sensors such that their fields of view would just overlap to create an accurate output
I designed a circuit to process the input signal of the infrared sensor into a output for the LED screen
Phase Two: Programing & Calibration
Phase Two: Programing & Calibration
After programming and modifying the infrared sensor to output an analog signal rather a digital signal, I created a calibration curve by measuring the voltage put out by the sensor when "seeing" and comparing that to the temperature measure by an IR thermometer.
Phase Three: Building
Phase Three: Building
After successfully creating one working circuit, I worked to create 8 more identical circuits to create the 3x3 "display"

Testing the Infrared Camera with a hot resistor
Testing with my hand. Notice the lower LED intensity compared to the resistor video.
