An imaging or sensor system comprises a transmitter assembly,
a receiver assembly and a control unit. The transmitter
assembly defines an outgoing optical beam transmission path
with respect to a target surface and the receiver assembly
defines a return optical signal transmission path from the
target surface. Each of the paths includes transmission
through or reflection from at least one microdisplay device
comprising a plurality of controllable elements for selective
placement in a transmit mode for transmission of light along
the transmission paths. A control unit selectively places the
microdisplay device elements in the transmission mode.

The Lander is an underwater research platfonn that is capable of carrying a variety of scientific instruments. The largest instrumental package that can be attached consists of a continuous wave laser transmitter, a pulse modulated laser transmitter, an Altimeter, an AC-9 optical sensor, a conductivity temperature and depth sensor, an LISST optical sensor, a GPS beacon and an acoustic modem. The continuous wave laser transmitter housing consists of a variable power single mode low noise OEM laser and a galvanometer scanner and is mounted on a pan and tilt unit. The rest of the instruments are attached to the frame of the Lander using various fixtures. There is also an acoustic release attached to the back of the frame which is to be used for retrieval purposes.
