A/D Integration

A/D integration is a method to reduce the influence of noise by obtaining a simple average for a certain period because the frequency of noise is often similar to the frequency of the commercial power supply.

A/D Resolution

Resolution of A/D conversion. It is normally expressed with the number of bits.
With 8-bit resolution, the minimum resolution of the A/D conversion is a value of "2 raised to the 8th power = 256 divisions". It should be noted that many instruments specify their resolution by rounding the noise components inside the instrument, so that the specified resolution may differ from the resolution of the actual A/D conversion.

Aberration

This refers to color smudges and distortions of an image. This can be compensated for by combining multiple lenses.

Allowable Signal Source Resistance

The resistance allowed to the signal source. The value is determined with the exactness and internal circuit of the instrument.

Ambient light

The maximum amount of ambient light received by the light-receiving surface of the sensor that allows a sensor to function normally.

Averaging

A method to collect data by repeating the moving average calculation the number of specified times, in order to cope with data dispersion which cannot be solved only with the AD integration time. The number of averaging calculations is specified before data collection starts. The data is stored after the moving average calculation is conducted.
