In the 1960 s, interest turned to the oxidation of perfluorocarbons. In the United States, much work has been done at the Aerospace Corporation Photochemical, thermal, electric-discharge, and flame studies, as well as oxidation initiated by oxygen atoms and ozone, were performed in El Segundo, California. High-temperature studies were performed at the...

The imager proposed in US-A-5030828 (Grumman Aerospace Corporation, USA, 09.07.91) has parallel elongate cavities formed within a substrate, photosensitive detector elements formed within the cavities and an optical insulating layer adjacent each of the cavities to optically isolate the cavities from each other. The elongate cavities provide an increased detector element surface area which increases the sensitivity. The optical isolation reduces cross-talk among adjacent detector elements. 

A method for aligning detector arrays on the surface of a signal processing module is shown in US-A-5075201 (Grumman Aerospace Corporation, USA, 24.12.91). 

The module of another embodiment uses a set of various sized wafers 152 stacked to form a mesa structure with the edges of the wafers comprising shelves 154. Each wafer has a pattern of metallized holes 156 therethrough, and a series of terminal pads 158 on the shelves. The method of manufacturing the imager is claimed in US-A-3970990 (Grumman Aerospace Corporation, USA, 20.07.76). 

In US-A-4618763 (Grumman Aerospace Corporation, USA, 21.10.86) a detector module is disclosed which is formed of stacked multi-channel integrated circuits, a detector array and a module header interface. The detector array and the module header interface are disposed transverse to the plane of the integrated circuits on opposite edge portions of the integrated circuits. Each integrated circuit is formed in a semiconductor material which has been deposited upon a thin sapphire wafer. 

One problem which arises when a detector array is attached to the face of a multi-layer module is the inability of the detector material to absorb forces generated by a mismatch of coefficient of thermal expansion between the detector array material and the module. Furthermore, it is difficult to isolate a fault that may be attributable to either the detector elements, module wiring or processing elements. A buffer board is introduced in WO-A-8807764 (Grumman Aerospace Corporation, USA, 06.10.88) which facilitates electrical communication between the detector elements and the module and conductive patterns formed on the module layers, and also enhances the structural characteristics and separate testability of the system components. 

GaAs, CdTe and HgCdTe are deposited epitaxially on a silicon substrate in US-A-4910154 (Ford Aerospace Corporation, USA, 20.03.90). If islands of individual detector elements are formed, the deposited layers will have a combined thickness which makes it difficult to interconnect the detector elements with corresponding silicon circuitry due to the steep sides of the detector elements. It is therefore proposed to grow the GaAs, CdTe and HgCdTe layers in recesses formed in the silicon substrate, and interconnect with a planar technology.

Laboratory Techniques. In addition to the previous research programs which address the personnel and management information needs of forensic science laboratories, the National Institute is funding research to improve instrumentation and analytical techniques applied to the analysis of physical evidence. The Aerospace Corporation of El Segundo, California, and the Law Enforcement Standards Laboratory of the National Bureau of Standards (NBS) have served as prime contractors to the Institute in the laboratory technique area. Although space does not permit a complete discussion of all projects underway at Aerospace and NBS, I will describe two project areas which are of great interest to forensic science practitioners and researchers. 

Blood and bloodstain analysis. The Aerospace Corporation has completed a survey and technical assessment of the state-of-the-art of forensic serological practices in the United States. Problems have been defined which currently limit the utilization of blood characterization techniques, and approaches have been identified which have the potential of solving these problems. This assessment was accomplished primarily through contacts with criminalistics laboratories, blood banks, industrial organizations which manufacture instrumentation and reagents for blood identification, and through an extensive search of the literature. 

From what has been learned over the past year during this assessment phase, The Aerospace Corporation and its subcontractors will be concentrating now on the development of better blood identification methodologies. Improved immunological and electrophoretic methods, as well as combinations of these and other new methods, are being explored for application to the forensic serology problem. Other new blood systems with even higher discrimination capabilities are known but have yet to be adapted for use with dried blood. 

The above project is being closely coordinated with the bloodstain research program being carried out by the Aerospace Corporation. 

The effort of the entire staff of the Forensic Science Laboratory at The Aerospace Corporation is acknowledged. Particular thanks are extended to A. R. Calloway, D. J. Carre, Q. Kwan, and R. Nesbitt. The author also benefited from numerous discussions with Dr. S. Siegel.
