Abstract : The camera experiment controller interface provides communications between an HP9845 desk-top computer and a digital camera instrumentation set. It is used with two cameras in separate experiments. One camera is in an underwater housing used for measurement of beam spread function. The second camera is used aboard the vessel at the output focal plane of an optical spectrograph. The digital camera set includes the 100 x 100 pixel digital Reticon camera with its RS250 controller, the ITT microchannel plate image intensifier with its electronic gate or shutter, and a Graflex strobe light source. The interface sends all the electronic signals needed to control the instrumentation set. The HP9845, in turn, programs the interface with the timings required for the desired experiment. The HP9845 also reads out image data stored in a 16K x 8-bit memory in the interface. Thus, two independent levels of operation take place in the interface: control of the camera experiment; and data communication between the HP9845 and digital camera. Both levels of operation are discussed in this document.
