LED-Based Photometric Stereo-Imaging Employing Frequency-Division Multiple Access

We present a photometric stereo-imaging approach based on illumination with light-emitting diodes (LEDs) from different angles where the LEDs are sinusoidally modulated and do not require synchronization with each other or with the camera.
