In order to make it feasible to obtain a differential phase image having a uniform brightness and good quality, a scanning type optical microscope comprises: a laser light source; an objective lens for collecting, onto an object under observation, a light beam emitting from the laser light source; a scanning light deflector disposed between the laser light source and the objective lens; a light detector comprised of a plurality of photoelectric converters receiving a light from the object and being separated into two sections; a signal processing circuit for calculating the difference between the signals coming from the two sections of the light detector to thereby obtain a differential phase signal; and adjusting means for adjusting the differential phase signal with a signal varying with an image height and being synchronous with the scanning of the light beam.
