They are here reported the developments and experimental results of fully operating matrices of spectrally tunable pixels
based on the Transverse Field Detector (TFD). Unlike several digital imaging sensors based on color filter arrays or
layered junctions, the TFD has the peculiar feature of having electrically tunable spectral sensitivities. In this way the
sensor color space is not fixed a priori but can be real-time adjusted, e.g. for a better adaptation to the scene content or
for multispectral capture. These advantages come at the cost of an increased complexity both for the photosensitive
elements and for the readout electronics. The challenges in the realization of a matrix of TFD pixels are analyzed in this
work. First experimental results on an 8x8 (x 3 colors) and on a 64x64 (x 3 colors) matrix will be presented and analyzed
in terms of colorimetric and noise performance, and compared to simulation predictions.
