Commercially available photon tunneling microscopes have a lateral resolution of 160 nm but subnanometer vertical resolution. The nondestmctive, instantaneous 3-D viewing of a surface (no scanning) yields real-time imaging as one traverses a given sample. The sample must be a dielectric, but transparent polymer tepHcas of opaque samples can be studied.

The scanning transmission electron microscope (STEM) was used to directly observe nm size crystallites of supported platinum, palladium and first row transition metals. The objective of these studies was to determine the uniformity of size and mass of these crystallites and when feasible structural features. STEM analysis and temperature programmed desorption (TPD) of hydrogen Indicate that the 2 nm platinum crystallites supported on alumina are uniform In size and mass while platinum crystallites 3 to 4 nm in size vary by a factor of three-fold In mass. Analysis by STEM of platinum-palladium dn alumina established the segregation of platinum and palladium for the majority of crystallites analyzed even after exposure to elevated temperatures. Direct observation of nickel, cobalt, or iron crystallites on alumina was very difficult, however, the use of direct elemental analysis of 4-6 nm areas and real time Imaging capabilities of up to 20 Mx enabled direct analyses of these transition metals to be made. Additional analyses by TPD of hydrogen and photoacoustic spectroscopy (PAS) were made to support the STEM observations. 

Step movement during chemisorption appears to be a general phenomenon. Real-time images observed (Figure 4.4) for chlorine chemisorption at Cu(110) indicate that nucleation takes place at a defect site, resulting in a single string... 

Figure 6.6 Real-time images of oxygen chemisorption at 290 K at a Cu( 11 ())- Cs overlayer, ctCs = 1.5 x 1014cm-2. The black dots identify identical surface positions in the three images. Note the transformation of the surface from rows running in the < 110 > direction to rows running in the < 100 > direction and also changes in the step structure. (Reproduced from Ref. 16).

In the field of imaging, present-day software should use mouse-driven or menu-selectable commands to control the camera and allow real-time image capture. The latter feature allows the users to monitor the image buildup and trigger the capture at the best moment. Temperature control and exposure times should... 

The axon comprises a major portion of the total volume and surface area in most neurons and may extend several thousand cell body diameters. Since the genetic material and nearly all the protein synthesis machinery are localized to the cell body, a supply line is maintained to provide structural and functional materials to sites all along the length of the axon. Insights as to how neurons accomplish this task can be obtained by real-time imaging of living axons with video-enhanced light microscopy [1] (Fig. 28-1).

Using a pilot system at Waseda University, we have been able to develop the technology and the concept of digital optics for the radio patrol camera. The present pilot system is an eight elements 1 dimensional array. So, the picture points are eight. The wide view and the real time image formation have been established in this system.
