Abstract
An example embodiment includes an apparatus for monitoring launch parameters of an object. The apparatus includes a transmitter optical subassembly (TOSA), a receiver optical subassembly (ROSA), a processing unit, and a camera. The TOSA includes at least one laser source configured to transmit a laser sheet along an expected flight path of an object. The ROSA is configured to receive light reflected from the object. The processing unit is configured to estimate a velocity of the object based at least partially on the received light. The camera is configured to capture one or more images of the object at a time in which the object passes through a field of view of the camera according to the estimated velocity.
