We propose a method to perform color imaging with a single photodiode by using
light structured illumination generated with a low-cost color LED array. The LED array is
used to generate a sequence of color Hadamard patterns which are projected onto the object
by a simple optical system while the photodiode records the light intensity. A field
programmable gate array (FPGA) controls the LED panel allowing us to obtain high refresh
rates up to 10 kHz. The system is extended to 3D imaging by simply adding a low number of
photodiodes at different locations. The 3D shape of the object is obtained by using a noncalibrated
photometric stereo technique. Experimental results are provided for an LED array
with 32 × 32 elements. [-]
