Systems and methods for generating three-dimensional images of an object based on frustrated total internal reflection

A method for generating a three-dimensional representation of a surface using frustrated total internal reflection, the method being implemented by a computer system including one or more physical processors and storage media storing machine-readable instructions, the method comprising:

• obtaining a two-dimensional image of an object in close proximity to an imaging surface, wherein the two-dimensional image is generated based on electromagnetic radiation reflected from the imaging surface and received by a sensor device of an imaging system;
• determining an intensity of the electromagnetic radiation received for individual points on the object;
• determining a distance between the imaging surface and the object at each of the individual points based on a correlation between the electromagnetic radiation transmitted towards the imaging surface and the electromagnetic radiation reflected from the imaging surface, wherein the determined intensity of the electromagnetic radiation indicates the electromagnetic radiation reflected from the imaging surface;
• and
• generating a three-dimensional representation of the object based on the two-dimensional image and the determined distances between the imaging surface and the object at each of the individual points.
