Abstract
A method of detecting cellular types in a biological sample supported on an infrared absorptive substrate, such as a plain glass slide, analyzes infrared light reflected from the sample using an Attenuated Total Reflection (ATR) technique. An infrared beam is directed to the sample through an ATR microscope objective. The depth of penetration of the infrared beam in the sample is controlled to avoid infrared spectral response from the absorptive substrate. The attenuated total reflection from the sample is detected and analyzed to determine the cellular types or the presence of anomalies in the sample. The method allows infrared measurements on cell samples mounted on plain glass slides, as are normally used by pathologists and other medical investigators.
