      abstract     = {We present an update of the PhLAM-DESY project aiming at
                      developing novel electro-optic diagnostics destined to
                      record electron bunch shapes (and THz pulses in general).
                      When high repetition rate operation is needed, a very
                      efficient technique consists of probing the electric
                      waveform of interest in an electro-optically active crystal
                      using chirped laser probes. However, if used without special
                      care, this technique has also been known to present serious
                      limitations in terms of resolution and fidelity of the
                      measurements, especially in the case of long recording
                      windows and/or short electron bunches. In this study, we
                      explored solutions to this problem, that are based on the
                      so-called diversity concept.The principle is to design an
                      electro-optic measurement system with multiple outputs. For
                      special designs, it is possible to show that the information
                      is sufficient to faithfully retrieve the electric field to
                      be measured. We review the principle of the method,
                      numerical results, as well as the status of experimental
                      developments at European XFEL and FLASH.},
