Abstract
A device for determining a position of a horological display, the device including a control device coordinating a time base, a shape recognition device, and an optical acquisition device. The control device identifies the display and monitors its travel in order to code its instantaneous position in relation to a fixed guide-mark, and controls entries of its position at distinct instants in time to determine its mobility in relation to the fixed guide-mark. The device includes a device for determining the depth position of the display in relation to the fixed guide-mark, a device for controlling the position of the optical acquisition device, a device for controlling a focus of the optical acquisition device, and an additional optical acquisition device coupled with the optical acquisition device to interferentially monitor the display.
