Frustrated total internal reflection (ftir)-based health parameter detection systems, methods, and devices

A health parameter detection system comprising:

• a platform formed of a transparent material, the platform including a measurement surface operable to contact a target area of a user;
• a light source operable to transmit light into the transparent material;
• one or more cameras directed at the transparent material such that the one or more cameras is operable to receive a scattered light caused by a frustrated total internal reflection (FTIR) event occurring at the measurement surface because of contact with the target area;
• and
• one or more motors operable to move the measurement surface.

A method of health parameter detection, the method comprising:

• collecting calibration light data by powering a light source for a predetermined calibration time interval, the light source being adjacent to a transparent material forming a measurement surface;
• collecting test data by powering the light source during a testing time interval to perform a two-part assessment of a subject, the test data corresponding to one or more frustrated total internal reflection (FTIR) events occurring at the measurement surface caused by powering the light source for a testing time interval;
• normalizing the test data to generate normalized test data;
• and
• causing a visual representation of the normalized test data to be presented at a graphical user interface on a display of a clinician computing device.
