Abstract:
An infrared ray spectroscopy analyzer includes a light source unit, an attenuation prism, and a detecting unit-photosensitive array assembly. The light source unit is composed of two or more infrared light sources, and is positioned on the bottom of one side of the attenuation prism where beams radiated from the infrared light sources enter along a direction vertical to a direction of passing the attenuation prism. The attenuation prism has a rectangular ladder shape and has both sides forming inclined planes. A sample is placed on the attenuation prism. The detecting unit-photosensitive array assembly comprises: a detecting unit where a linear variable filter (LVF) with a high sensitivity to a specific wavelength band is mounted in order to generate an optical spectrum; and a photosensitive array which detects the spectrum in the detecting unit. In addition, the detecting unit-photosensitive array assembly is positioned on the bottom of the other side of the attenuation prism where beams radiated from the infrared light sources enter along a direction vertical to a direction of passing the attenuation prism. Therefore, the infrared ray spectroscopy analyzer can accurately measure and analyze a minimum sample with a low concentration by maximizing an effective signal, maximizing a signal to noise ratio (SNR), and ensuring the collimation of the optical source.

Abstract:
A cascade type interferometric nonlinear imaging apparatus based on CARS(Coherent Anti-Stokes Raman Scattering) is provided to improve medium molecule detecting sensitivity of a measuring sample by exciting medium molecules of a standard sample to allow the phase difference between beams passing through the measuring sample to be modulated. A cascade type interferometric nonlinear imaging apparatus based on CARS comprises a light source(10), a phase change device(30), a scan device(40) and a detector(60). The light source generates stokes light(1) having arbitrary frequency band and pump light(2) for exciting medium molecules of a sample with the stokes light. The phase change device allows the Stokes light and the pump light generated from the light source to pass through a standard sample(20), and changes the phase of the passed light and anti-stokes light on the same path. The scan device scans the phase-changed light to the space of a measuring sample(50). The detector measures light interference by using a phase difference between a light signal generated passing through the measuring sample by the scan device, and the light signal passed through the standard sample.
