Abstract
The preferred embodiment of this invention is illustrated in FIG. 2 showing an ultrasonic holographic imaging apparatus 50 having a multiple lens system 52 that is capable of providing both zoom and focus capability. The system 52 includes lens 54 and 56 that are independently mounted on lead screws 62 and 64 for movement relative to each other along an optical axis 57. The movement of the system is controlled by drive system 66 and 68 that have encoders 72 and 74 for accurately positioning the lens 54 and 56 relative to each other in response to signals from a microcontroller 76. The microcontroller 76 is operator controlled through control device 78 and 80 to provide both zoom capability and a focus capability.
