Measurements of pole figures with a low cost interface

An old Philips PW 1078/24 was updated with two stepping motors and software to measure texture scans. A programmable interface based on an Intel 8052AH microcontroler was built for us, which enables the texture goniometer to measure up to 20 scans. This interface is suitable therefore to be customized for special needs of any laboratory; the device furthermore is autonomous since once running, the computer can be used for other tasks. The adaptation to the texture and powder goniometers is straightforward. The cost of this interface is very low compared with the expenses for adaptation of parts of modern diffractometers.
