Abstract
During the past decade research has been in progress on various techniques and devices which in the next decade will probably become elements of new infrared instrumentation. In this paper some of these techniques and devices will be discussed. They include such things as narrowband filters, new varieties of sources, and interference spectroscopy. An attempt will be made to show some examples of new infrared instrumentation which might arise from some of these tools. Infrared spectroscopy as it is used today in structure analysis and in chemical analysis is frequently limited by the resolution which can be obtained. The resolution limit in existing instruments in the near infrared appears to be set by the optics rather than by the detector. With the narrowband filters now being developed and with interference spectroscopy, it should be possible to extend the resolution limit beyond present instrumentation to the point where it is again limited by receiver sensitivity. Some experiments will be shown which will indicate the magnitude of the resolution increase.
