The fundamental characteristics of analytical stereoplotters compared to the analog stereoplotters is their facility to use them and the versatility given by the on-line of a mini-computer. Analog stereoplotters, even those classified universal, are

An optical communication link using a micromachined corner cube reflector (CCR) was demonstrated to transmit digital signals over a range of 2 meters by reflecting an interrogating laser from a 5mW laser source. The surface micromachined CCRs are mad
