Abstract
A laser diagnostic unit for detection of carcinosis and method of detecting carcinosis in a patient by examining a specimen taken from the patient. The laser diagnostic unit includes a specimen well for retaining the specimen therein and a laser for irradiating the specimen within the specimen well. A monochromator having an entrance slit receives light scattered by the specimen within the specimen well through the slit and a photomultiplier for converting light dispersed in said monochromator into electrical signals. The electrical signals are provided to a microprocessor for analyzing the signals and generate a spectrogram of the laser light irradiating the specimen. The spectrogram will indicate that the specimen is cancerous upon detection of differences with a spectrogram created by irradiation of a non-cancerous specimen. The laser used to irradiate the specimen is preferably an argon laser and a power source is connected to the argon laser and is able to regulate a current supplied to the argon laser, thereby regulating the wavelength of the light beam produced by the argon laser.
