Optical Displacement Sensor LabVIEW Integration


Industry Life Science
   
Application Area Automated Tests, Machine Vision
   
Date December 2010

Challenge

Effectively control and manipulate the sensor system to a wide variety of applications and provide manageable access to the data obtained from the OD sensor system.

Solution

Integrate the SICK OD Sensors with LabVIEW, giving access and manipulation ability to the data received from the OD Sensor.
SICK OD Sensor


The SICK Optical Displacement Precision Sensor system contains a distance sensor and an amplifier. The amplifier has three sensor head connections, which allows the values obtained from each distance sensor to be displayed on the LCD of the amplifier. The values are displayed in numerical values of the distance in millimeters and a waveform that plots the intensity of the emitted energy to the number of pixels.

We were able to integrate the OD Precision Sensor with LabVIEW. An array can be made from the wavelength monitoring, which allows the capability to share data with the network. Giving anyone in the company the ability to access the data means that the data can be manipulated in different ways from different locations, providing convenience. For example, if glass pieces for a picture frame or a camera were on a conveyor belt and each glass piece must be a specific thickness, a troubleshooting program already integrated in the LabView code may be implemented to direct the glass piece with incorrect thickness to be rejected or redirected to a correction location. The same code may be implemented for making solar panels or cassettes used in X-rays for computed radiography, in which the cassettes that house the imaging plate must be correctly spaced. The distance sensor integrated with Labview can be used in various applications ranging from photography to medical devices.

The SICK OD Sensor can see through plastic and detect their top and bottom edges
