Balance Adjustment
The initial adjustment of a strain gauge. This adjustment sets the status to zero strain after attaching the strain gauge. With digital measuring instruments, the balance adjustment is complete by just pressing the button.Balance Adjustment Exactness
"The exactness (accuracy) of balance adjustment.It represents the amount of errors from the zero point after balance adjustment."
Band-pass filter (CCD method)
A band-pass filter only transmits light components with a specified wavelength. The band-pass filter incorporated into the VG Series receiver has a characteristic that only passes light components with the wavelength of the semiconductor laser used in the VG.Binarization (CCD method)
A signal output from the CCD image sensor is an analog signal. To use the signal for various measurements and differentiations, the analog signal must be first converted into a digital signal. To convert from analog to digital, a threshold (binary level) is set for the signal from the CCD image sensor, as shown below. Areas brighter than the threshold are defined as "bright", and areas darker than the threshold are defined as "dark". Thus, all areas are defined as either "bright" or "dark". This process is termed binarization, and digital signals corresponding to "bright" are defined as "1" (= HI), and those corresponding to "dark" are defined as "0" (= LO). The intersection of the signal from the CCD image sensor and the threshold is termed "edge". Detection of this "edge" is applied for various measurements and differentiations.Black Body

Brightness
Detailed observation cannot be performed with a lens that produces a dark image.Bubbling
When a laser beam is applied onto a base material, the heat vaporizes the material and generates gas and bubbles. The bubbles are trapped under the surface layer of the base material and create whitish bumps. With dark-colored base materials, the marking appears in a "lighter color of the base material" offering high visibility.Example: Black material -> Gray marking, Red material -> Pink marking
