results. This setting eliminates the problem.
For pixels with amplitude values smaller than the set value (weakly reflected light),
the distance and amplitude values are output as low amplitude values.
Refer to "4-17 MIN_AMP (for close distance) Setting (92Hex)" and "4-18 Get
MIN_AMP (for close distance) (93Hex)" for details.
- Enabling/disabling operation check LED
This setting switches between enabling and disabling operation check LED.
Refer to "4-20 Set Enabling/Disabling Operation Check LED (95Hex)" and "4-13 Get
Enabling/Disabling Operation Check LED (96Hex)" for details.
- Responder speed setting (transmission size/interval)
Response data may be occasionally lost. Adjusting the response speed by this
command can prevent the loss of response data.
If loss of response data occurred, make the transmission size smaller and the
interval longer. (The setting may degrade the frame rate)
Refer to "4-22 Response Speed Setting (97Hex)" and "4-23 Get Response Speed
(98Hex)" for details.
- ENR threshold
Occasionally the distance output at the boundary between the measurement target
and the background may become unstable. This setting eliminates the problem.
If the difference in distance between adjacent pixels is greater than the set value,
the farther pixel value is output as the lower amplitude value.
Refer to "4-24 ENR Threshold Setting (99Hex)" and "4-25 Get ENR Threshold
(9AHex)" for details.
③Specify the operation mode.
Use the operation mode setting command to set the desired mode.
This product has two operation modes: Normal mode and High-speed mode.
The normal mode is the default mode. It allows wider range of measurement than the
high-speed mode.
Perspective field of view
The normal mode allows
detection of two different
exposure times, A and B, and
this area can be measured.
Note that the frame rate is 10fps.
The high-speed mode increases the frame rate by about twice compared to the normal
mode. You must be careful about measurement of the followings:
- When the distances to the measurement targets vary widely from close to distant
- When the reflectivity of the measurement targets vary widely from low to high
