A novel golf ball launch monitor with a foldable design is disclosed. This launch monitor has a bottom housing that is connect to a top housing through a hinge. The top housing contains an image sensor for capturing an image of a golf ball. The top housing may also include a tilt gauge to measure the tilt of the top housing relative to the earth tangential or other reference plane. The monitor may also have a processor to process the images captured by the sensor, and may also include an illumination lamp to illuminate the golf ball and the surrounding environment. A display and/or a speaker may be added to the monitor as a means of outputting the results from the processor to a user of the monitor.
