Parameter

Description
Double speed
OFF
Enable / disable the double frame rate mode:
·
ON
- enabled, the scanner works in DS mode;
·
OFF
- disabled, the scanner works in standard mode.
Note:
In this mode, the linearity of the scanner for Z is reduced from
±0.05% to ±0.1% of the measuring range for Z.
Analog gain
6
Analog gain of the signal generated by each pixel of the image. Valid
values: from 1 to 15.
Digital gain
108
Digital gain of the signal generated by each pixel of the image. Valid
values: from 96 to 114.
Exposure time
(ns)
300000
The exposure time of the CMOS sensor (signal accumulation time) in
nanoseconds, step - 10 ns. The minimum value is 3000 ns, the
maximum possible value depends on the frame rate, the ROI and DS
modes, and is limited to 1/FPS.
Note:
The laser automatically turns on during the exposure time only.
Frame rate
484
The current number of profiles (frames) per second that the scanner
processes and transmits.
Exposure HDR
OFF
This mode is designed to expand the dynamic range of the sensor. It
is used in the control of complex objects containing areas with different
reflectivity. The expansion of the dynamic range is achieved due to the
use of a piecewise linear response of the CMOS sensor.
Autoexposure
OFF
Enable / disable the autoexposure mode:
·
OFF
- manual mode;
·
ON
- autoexposure mode.
Column EDR
OFF
This mode is designed to expand the dynamic range of the sensor. It
is used in the control of complex objects containing areas with different
reflectivity. The expansion of the dynamic range is achieved due to
different exposure times for the even and odd columns of the CMOS
sensor. For odd columns, the exposure time is lower. Exposure time
reduction is determined by the
Column exposure divider
coefficient.
Column exposure
divider
5
Exposure time reduction coefficient for odd columns of the CMOS
sensor. It determines how many times the exposure time for odd
columns is reduced relative to the main exposure time. It is available
only when the
Column EDR
mode is enabled. Possible values: 5, 10,
15, 20.
