Abstract:
1. An apparatus for analyzing cells in real-time comprising: a platform for a sample to be placed on; an infrared ray (IR) observation unit; and a signal processing unit for processing an IR signal received from the IR observation unit, wherein the IR observation unit comprises: a wavelength-tunable light source unit for irradiating light to a specific area of the sample, wherein the wavelength-tunable light source unit comprises a pumping light source and a non-linear wavelength-tunable means, and the non-linear wavelength-tunable means, and the non-linear wavelength-tunable means comprise a ferroelectric substrate, an optical waveguide of the ferroelectric substrate, so that the wavelength-tunable light source unit changes the wavelength of the light by the electric field applied through the electrode; an IR sensing unit for receiving the light which has been irradiated by the wavelength-tunable light source unit and passed through the sample, wherein the IR sensing unit comprises a filter for filtering the light which has passed through the sample to get the light within a predetermined wavelength range to pass through, a detector for receiving the light which has passed though the filter and generating the IR signal, a light condensing means for condensing the light which has passed through the filter to the detector; and a sensor position controlling means for controlling positions of the filter, the light condensing means and the detector; and an image sensing unit for alignment for checking the area of the sample which is being irradiated by the light from the wavelength-tunable light source unit.
