Irradiate Particles With An Infrared Laser Pointer And Green Laser
This new technology works by irradiating particles with an infrared laser pointer and a green laser. Infrared lasers deposit energy into particles, causing them to expand due to heat. Then the green laser light is scattered by these heated particles. A visible-wavelength camera is used to monitor this scattering, tracking the physical changes of individual particles through the lens of the microscope. The instrument can be used to identify the material composition of a single particle, by adjusting the infrared laser to different wavelengths, and collecting visible light scattered light at each wavelength. The slight heating of the particles will not bring permanent changes to the material. This makes the laser pointer technology an ideal choice for non-destructive analysis.

Excite infrared light particles and observe their scattering at visible wavelengths. This laser pointer light modulation process is called Mie scattering. Technology that has been used since the 1980s. This new research uses more advanced optical component manufacturing and detection, using Mie scattering and imaging configuration for the first time to detect multiple particles. We are actually imaging the field we are studying, and he is the technician and co-author of the study. "This means that we can simultaneously detect multiple particles on the surface at the same time. The new microscope uses visible light wavelengths for imaging, making it a spatial resolution of about 1 micron, which is better than the 10-micron resolution of traditional infrared spectroscopy methods. Many. This increased resolution allows the new laser pointer technology to distinguish and identify individual particles that are very small in size and tightly bound together.
