FAQs of Digital Image Correlation(DIC) Measurement System

What are the types of errors in DIC measurement? What are their sources? How can they be quantified?

DIC mainly has random errors and systematic errors. Random errors originate from camera noise, while systematic errors come from camera drift, heating, temperature variations, and vibrations. Random errors are quantified through spatial and temporal standard deviations. The spatial standard deviation is calculated by computing the spatial standard deviation of the Quantity of Interest (QOI) for each image, and then averaging the spatial standard deviations of all stationary images in the time domain. The temporal standard deviation is calculated by computing the standard deviation of the QOI for each sub-region in the time domain, and then averaging the temporal standard deviations of all sub-regions within the Region of Interest (ROI).

How to match and superimpose the deformation field and temperature field measured by DIC?

Calibrate and align the visible light camera with the infrared camera using an infrared calibration panel, so that the strain field and the temperature field are in the same coordinate system.

Can the speckle in DIC be replaced by a laser projection?

No. Although laser projection can produce high-brightness patterns, its inherent speckle phenomenon and characteristics such as uncontrollable randomness and uniqueness make it difficult to directly replace the speckle in DIC.

In what scenarios can 2D-DIC be used for approximate measurement? What are the quantitative indicators?

Measurement Scenarios for 2D-DIC: Plane specimen testing, small deformation measurement, and observation from specific viewpoints.

Quantitative Indicators: Displacement measurement accuracy, strain measurement accuracy, measurement range, resolution, and signal-to-noise ratio.

How accurate can displacement measurements be using DIC?

The theoretical displacement measurement accuracy can reach 0.01 pixels.

What is 3D Digital Image Correlation and how does it work?

3D Digital Image Correlation is a non-contact optical measurement technique that uses two or more cameras to track the displacement of a speckle pattern applied to a surface. By comparing images before and after deformation, our RDIC software calculates full-field 3D displacements and strains with micron-level accuracy. The process involves: 1) Applying a high-contrast speckle pattern, 2) Capturing synchronized images from multiple angles, 3) Calibrating the camera system, 4) Tracking pattern subsets through deformation, 5) Computing displacement fields and deriving strain tensors.

How accurate are displacement measurements using DIC?

The accuracy of Revealer DIC systems depends on several factors including camera resolution, calibration quality, and speckle pattern quality. Under optimal conditions:

Displacement accuracy: Typically 0.01-0.05 pixels (sub-micron with proper magnification)

Strain accuracy: 50-100 microstrain (με) for most applications

Calibration accuracy: <0.05% with our precision calibration targets

Our systems are benchmarked against laser interferometers to ensure measurement traceability.
