The commercially available version of Shack-Hartmann wavefront sensor

The development of low-cost Shack-Hartmann wavefront sensor (SHWS), based on USB2-interface of CMOS camera, is presented in this report. The description of main principle of SHWS and example of wavefront measurements are given. A comparative characteristics and spheres of sensors applications, based on USB-2 and IEEE-1394 types interfaces, are shown below. But certainly there are advantages and disadvantages of each type of these sensors. That is why each type has more suitable spheres of application. This is the subject of our discussions.
