Abstract
The present disclosure relates to an optical measuring apparatus. An embodiment of the present disclosure provides an optical measuring apparatus including a chamber portion including a first chamber accommodating a sample, and a second chamber providing a space in which light interference with scattered light emitted from the first chamber occurs, a light source portion irradiating input light toward the chamber portion, a sensor portion detecting speckles of output light that is output from the chamber portion, and a controller configured to estimate information about target particles in the sample by using the speckles of the detected output light.
Claims10
An optical measuring apparatus comprising:
- a chamber portion including a first chamber accommodating a sample, and a second chamber providing a space in which light interference with scattered light emitted from the first chamber occurs;
- a light source portion irradiating input light toward the chamber portion;
- a sensor portion detecting speckles of output light that is output from the chamber portion;
- and
- a controller configured to estimate information about target particles in the sample by using the speckles of the detected output light.
An optical measuring apparatus comprising:
- a light source portion generating input light;
- a chamber portion providing a space in which the input light input from the light source portion is multi-reflected or multi-scattered through multiple passages;
- a sensor portion detecting speckles of scattered light output from the chamber portion;
- a first polarization unit that is arranged between the chamber portion and the light source portion and arranged on an optical path of the input light;
- and
- a second polarization unit that is arranged between the chamber portion and the sensor portion, arranged on an optical path of the scattered light, and has a polarization axis crossing a polarization axis of the first polarization unit.
