Abstract
The laser of a laser-generated windshield display is controlled to initially deflect the laser beam in the direction of a reflective target disposed outside a display region of the windshield, and a sensor disposed in a reflection path of the target is sampled to detect the presence of a feedback signal that occurs when the laser beam impinges on the sensor. If the feedback signal is detected, the laser beam is deflected onto the display region to generate a driver display; but if the feedback signal is not detected, the laser is automatically turned-off. Once the laser is turned off for lack of a feedback signal, the control is repeated following a specified delay interval so that the driver display will automatically resume the when the condition that prevented generation of the feedback signal is cured.
