Prodcut Descripition

OCT (Optical Coherence Tomography) Thin Layer Imaging Detector is equipment using optical coherence tomography (OCT) technology to detect and image pearls, coatings and other thin materials, technology innovation and product performance are in a leading position both at home and abroad. Broad product application scope and wide prospect of market, it has been adopted by numerous laboratory and testing organizations.

 

Operating Principle

Optical Coherence tomography (Optical Coherence Tomography, OCT) is an imaging technique rapidly developed in nearly ten years, it uses basic principle coherent of light interferometer to detect back reflection or several scattering signal to the incident weak coherent light of different depth levels. By scanning, it can get broken two-dimensional or three-dimensional structure image in real-time.

 

Application:

Detection of pearl, coating materials and other thin translucent materials. Imaging depth up to 3 mm in highly scattering biological tissue.

 

Features

-High sensitivity and resolution: high resolution can achieve 5~15m, clear and real image, detect data is very accurate.

-Fast detection speed: imaging rate reaches 1 picture/s, can realize real-time imaging and online detection, scanning speed of frequency-domain scanning system can reach 40000Hz/s, can realize real-time 3d imaging.

-Nondestructive no radiation: no damage to the seized material to complete the detection, and exposure to the seized material's optical power was only 1~2mW, cannot produce any damage and radiation.

-Non-contact: The probe doesnt need to contact with the surface of detection tissue.

 

Main Technical Parameters:

-Light wavelengths: 1300nm

-Light source power: 5mW

-Sample area light power: 1~2mW

-Vertical resolution: 20m

-Transverse resolution: 20m

-Scanning depth: 3mm

-Imaging velocity: 1~2p/s

-Working distance: 50~70mm

 

Example:

Pearl detection:

Using the system to detect pearl can realize real-time faultage imaging nondestructively no radioactively, thus analysising, measuring and evaluating the quality of pearl.

Product advantage:

Accurate detection data: intuitive pearl nacre image, accurate measuring nacre thickness of pearl, resolution can reach 0.03mm.

Fast imaging detection speed: each sample use only 1-2 seconds, optional sorting device, suitable for pearl breeding, grading, screening of producing process.

Small portable: instrument miniaturization, easy for installation and using, can be directly used in production factory, testing organization, distribution unit and retail unit, Also applies to flow detection.

In addition, compared to the traditional using X-ray to transmission imaging detection to the pearl, This system uses a innovative contactless backscattering imaging technology to achieve the simple pearl detection, make measuring semi-finished products and finished pearl ornament products comes true. For its no radioactivity, completely no damage to detect workers and pearl sample, the testing laboratory dont need any radioactive shielding, and no potentially X-ray radioactive hazards to workers.
