Abstract: Systems and methods are disclosed for improving the resolution and quality of an image formed by signals from an array of receivers. Multiple receivers introduce variations in arrival times that can be less than the period of an operating signal, and also less than the period associated with a sampling operation. Thus, multiple receivers allow sampling of fine features of reflected signals that would be considered beyond the resolution associated with the operating signal. Use of multiple receivers also provides an effective sampling rate that is greater than the sampling rate of an individual receiver. Similar advantages can be obtained using multiple transmitters. Such advantageous features can be used to obtain high resolution images of objects in a medium in applications such as ultrasound imaging. Sub-Nyquist sampling is discussed.

Abstract: A rigid endoscope includes a jacket tube with an optical system and, parallel to the optical axis of the optical system, a first glass fiber bundle which emits a beam to illuminate an object to be examined. A second optical illumination system is directed at the object being examined. The second light exit of the second optical illumination system is recessed from the first light exit of the optical system by a distance greater than a diameter of the jacket tube. The light exit axis at the second light exit of the second optical illumination system is offset laterally relative to the image axis at the distal end of the optical system by an amount such that because of the resultant parallax and the shadow formation and unequal light distribution thus attained, the vividness of the image impression for three dimensional objects is increased.
