%X In an amplitude grating system of small grid pitch,the diffractive light is the main cause to deteriorate the contrast and sinusoidal property of Moiré signals.The relations between the phase of ± 1st order Moiré fringes and other factors,such as the space of grating pair,are analyzed.It is proposed to use ± 1st order Moiré frings to obtain high quality Moiré signals.Experimental results agree with the theory results well.
