LMI sensors are available in micrometer beam sensor, single-point, multi-point and laser line configurations with ranges from nanometers to over 4 meters. All of the sensors are manufactured to high quality specifications, and backed by a company with a long history in vision systems and their applications.

General Purpose sensors are designed to accommodate a wide variety of quality control applications.

Brandname Specific sensors are mostly related to a specific industry such as automotive, sawmill or molten metal measurement. (e.g. DynaVision, Diffracto, Selcom)

Custom OEM sensors are specifically designed to fit a custom application for an equipment manufacturer. These sensors are used in volume by OEMs to fit their industry and design constraints.

General Purpose Sensors

Single Point

Single Point sensors are most commonly used for on-line thickness gauging, distance measurement, profiling moving parts,etc. LMI Technologies designs and manufactures both digital sensors, and PSD-based sensors offering update rates to 500 kHz. These sensors come in a variety of shapes and sizes, and have ranges from nanometers to meters.

Multi Point

LMI B8 Multi Point Sensor

Multipoint sensors are often designed for specific application. Laser scan heads with multiple points are used in the sawmill for edger and trimmer optimization, and in the aluminum business for scalping applications. They can be used for many on-line sheet applications where a 3D profile is beneficial to the manufacturing process.

The Next Generation of 3-D Snapshot Scanning

Dual cameras allow the L4 Snapshot Scanner to more accurately collect a 3-D log profile, as it can see around irregularities found on all logs. A single camera system cannot do this. With multiple lasers in each head and high frame rates, the L4 can be used for snapshot scanning to collect "instantaneous" profiles at 12" (305 mm) spacing, or can continuously collect profiles every 1" (25 mm) for logs moving at 300' (91m) per minute.

The L4 is perfect for carriages, sharp chain, or bucking applications or small log breakdown when there is insufficient room for a double length infeed.

Surface Quality Inspection

DSight is a patented optical image enhancement technique that allows comprehensive surface inspection of sheet metal, glass, plastics, and tooling irregularities. DSight converts variations in surface curvature to changes in light intensity. The resulting images dramatically indicate surface anomalies as small as a few microns.

DSight systems are provided with camera and integral light source, reflective screen and Windows based image capture and analysis PC. With DSight systems, users can:

Magnify and display surface defects for easy interpretation

Store and compare images from several parts

Apply image processing algorithms to rate severity of defects

Glass Thickness Systems

Glass Thickness Systems are based on a triangulation sensor specifically designed to measure both sides of a glass panel with one laser beam. Since it operates from one side of the glass, it can measure thickness at any point on a large panel. Non-contact operation makes the systems capable of both off-line and in-line operation, at fixed positions or on scanning mechanism.

LASER BEAM (SHADOW) SENSORS

Shadow measurement uses a separate emitter and receiver, and operate like an optical comparator with automated digital readout. The emitter contains a laser diode, which projects a modulated laser beam onto the receiver. The beam height is determined by the optics (lenses) chosen, while the shape of the beam is controlled by auxiliary diaphragms. The diaphragms are adjusted to each application to achieve optimal accuracy.

The portion of the light emitted that reaches the receiver depends on the dimensions of the object in the light beam. The amount of light reaching the receiver is the difference between the amount of light emitted by the emitter and the cross-sectional surface area of the object. The measurement accuracy depends on the dimensions of the light beam determined by the diaphragm.

Three models of Beam Sensors are available, the standard LBS series, the miniature size MBS, and the larger field of view BBS. All provide high speed analog output.
