The image recorded on the holographic plate is called a hologram of the target, which carries both the amplitude and phase of the returned, scattered beam from the target. The first exposure of the holographic plate by the reference beam results in a reference hologram, while the second exposure by the returned beam imposes all changes of the target to the reference hologram.  2, record 1, English, - reference%20hologram

Record number: 3, Textual support number: 1 OBS

Target distance is proportional to the horizontal position of the deflection from one end of the time base, and target echo signal intensity is proportional to the amplitude of the vertical deflection. On some scopes the display is rotated 90°, so the time base is vertical and the signal pips increase from left to right horizontally.  6, record 3, English, - type%20A%20display

When both the amplitude and the phase information are available, it is possible to synthesize the polarization response for all the polarization states. To synthesize the response, phase information and two orthogonal(transmit and receive) polarization states are required. For example, most spaceborne SAR's(e. g. RADARSAT-2) use the HH and VV polarization configuration to satisfy the orthogonality condition. Three dimensional polarization response plots are typically used to illustrate the polarimetry response for a given target. The following conventions are commonly used : The radar response is normalized between 0 and 1 [. ] The horizontal axes are the ellipticity angle... and the orientation angle... The ellipticity angle ranges between-45°(right circularly polarized) and +45°(left circularly polarized). When [ellipticity angle equals 0°, we have linear polarization. The orientation angle... is usually defined between-90° and +90°, but is sometimes defined between 0° and +180°.  2, record 6, English, - ellipticity%20angle

The Positron Microscope was designed and built to be a hybrid instrument capable of performing several types of positrons and electron microscopy. For both electrons and positrons the microscope can be run in one of two modes : magnifying mode in which particles leaving the target are focussed onto a CEMA plate assembly to form a magnified image and scanning mode in which the amplitude of a signal is recorded as a function of the position(and possibly energy) of the incident beam. As an electron microscope the instrument will be able to operate in both magnifying and scanning(SEM) modes. As a positron microscope, however, source considerations will limit its immediate use to magnifying mode, i. e. positron reemission microscopy.  2, record 7, English, - positron%20microscope
