■ Polarize Angle And Degree mode

This mode calculates Polarize Angle and Polarize Degree in real time and outputs data.

Polarize Angle : The polarization angle producing the greatest luminance for a given pixel block.

(also referred to as AoLP: The Angle of Linear Polarization)

Intensity values assigned to pixels represent angles from 0 to 180˚.

Polarize Degree : The proportion of polarized light contained within the total light falling on a

pixel block.

(also referred to as DoLP: The Degree of Linear Polarization)

Intensity values represent proportions of polarized light from 0 to 100%.

As shown in the figure below, two polarimetric parameters of Polarize Angle and Polarize Degree

are calculated for a given pixel block and output from it.

As shown below, AoLP and DoLP data are alternately output as a single line of data

representing the first two lines from the image sensor.

The number of lines of output data is 1028 lines, which is half of the number of sensor lines.
