  We present a technique called single-pixel imaging camera based on
complementary detection and optimized Bernoulli modulation (CSPI camera), which
can significantly reduce the influence of the disturbance light to single-pixel
imaging (SPI). The numerical simulation demonstrates that when the probability
of the value "1" is P=0.5 for each coded pattern, CSPI camera is
disturbance-free is still disturbance-free even if the intensity fluctuation of
the disturbance light is much larger than the signal's intensity. The
reconstruction results of both SPI and differential SPI are also compared. This
technique of CSPI camera can dramatically promote real application of
single-pixel imaging Lidar.
