001 · Introduction

Consistent, defect-free surfaces — with laser precision.

Tiny bumps, dents, or rough patches can lead to premature wear, leakage, noise, coating failures, or customer complaints.

Intelgic's Surface Smoothness Inspection System uses laser profile sensors and triangulation-based point laser sensors to measure surface roughness and automatically flag areas outside acceptable thresholds. When smoothness crosses your defined limit, the system generates instant alerts so you react before defective parts move further down the line.

002 · Surface Profile Inspection

One technology, multiple types of surface inspection applications.

Intelgic uses laser profiler–based, contactless inspection to scan metal, wood, plastic, and other surfaces. The system verifies whether the surface is smooth, flat, textured, or formed according to the required design profile.

METHOD · A

Surface Smoothness Inspection

For flat or finished surfaces, Intelgic uses laser profilers to inspect surface smoothness and detect unwanted roughness or unevenness.

  • »Scan the surface without physical contact
  • »Measure height variation across the scanned area
  • » Detect roughness, waviness, dents, peaks, ripples, and uneven regions
  • »Compare the surface condition against acceptable thresholds
  • »Generate alerts when the surface is not smooth or does not meet quality requirements

Ideal for applications where the surface must remain flat, smooth, and free from visible or measurable irregularities.

METHOD · B

Design Profile Matching

For surfaces with a specific shape, contour, groove, curve, or engineered profile, Intelgic uses laser profiler data to compare the actual surface against the intended design profile.

  • »Capture the actual surface profile using a laser profiler
  • »Compare the scanned profile with the golden reference or CAD/design profile
  • »Detect missing, incorrect, deformed, or out-of-tolerance profile features
  • »Measure dimensional deviations across the scanned region
  • »Raise alerts when the surface profile does not match the required design
  • »Ideal for parts where the surface is intentionally shaped and must match a specific design, profile, or dimensional requirement.

The result is a high-precision, contactless inspection system that checks whether a surface is smooth, flat, or correctly profiled—and immediately alerts when it is not according to design.

003 · Workflow

How the inspection works.

Four sequenced stages — positioning, laser acquisition, thresholding, reporting.

STEP 01

Part Positioning & Triggering

Parts are inspected in-line on a conveyor or stationary on a fixture.

Triggered automatically (sensor/encoder) or by an operator button.

STEP 02

Laser Measurement & Acquisition

Profile / 3D

  • · Laser line / structured light projected onto surface
  • · Camera reconstructs surface profile or height map
  • · Software calculates roughness, deviations, anomalies

Point Laser

  • · Point laser projected at predefined locations
  • · Triangulation reads micro height changes
  • · Multi-point sampling builds roughness profile
STEP 03

Thresholding & Alerts

Engineers configure roughness tolerances per product / recipe. If measured values exceed tolerance, the system:

  • »Flags the part as Fail/Reject
  • »Highlights where the issue was detected
  • »Sends alerts to operators / QA team
STEP 04

Reporting & Traceability

Results logged in Intelgic's Certainty AI software or your existing system via integration.

  • »Part-wise pass/fail records
  • »Roughness measurements per point / profile
  • »Shift, batch, lot-wise statistics
  • »Exportable reports & dashboards
004 · Smart Compromise

When full 3D isn't practical.

For wider sheets, panels, long profiles, slabs, rolls, and structural parts, full 3D inspection can be expensive (multiple cameras, large optics, complex mechanics) and overkill when only key functional areas need validation.

Intelgic's triangulation-based point laser solution solves this by:

01

Measuring surface smoothness at critical reference points.

02

Using simple mechanical motion (linear slides, rotary stages) to scan multiple points.

03

Keeping hardware cost and complexity lower — while still giving quantitative, repeatable data.

04

Enabling surface smoothness inspection where full 3D is not feasible but quality still matters.

Q01What is a surface smoothness inspection system?
A surface smoothness inspection system uses laser sensors (laser profile/3D cameras or triangulation point lasers) to measure the roughness and micro-deviations on a surface. It ensures the surface meets your defined smoothness threshold and alerts you when it crosses the acceptable limits.
Q02How does Intelgic measure surface roughness?

Intelgic uses two technologies:

  • »Laser Profile Sensors / 3D Cameras for full-area profiling and high-resolution 3D reconstruction.
  • »Triangulation Point Laser Sensors for surface height at specific points via the triangulation principle.

Both methods give accurate, repeatable roughness values based on thresholds defined in the recipe.

Q03When should I choose triangulation over a 3D laser profile?

Triangulation point lasers are ideal when:

  • »The product surface is large or wide
  • »Full 3D scanning is not required
  • »Budget constraints make 3D cameras impractical
  • »Only critical points on the surface need evaluation

This method provides cost-effective and reliable roughness data.

Q04Can Intelgic measure roughness across the entire surface?

Yes. Using laser profile sensors or 3D cameras, Intelgic can perform full-area scans.

For large surfaces where full-area 3D scanning is impractical or too costly, we measure roughness at selected key points using triangulation lasers.

Q05What types of defects can this system detect?

The system can detect:

  • »Rough patches
  • »Height variations
  • »Micro-dents or peaks
  • »Waviness and bumps

Q07Will the system work on moving parts or only stationary ones?

Both options are supported.

  • »In-line inspection on conveyors using automatic triggers / encoders
  • »Stationary inspection where the operator loads a part and triggers the scan

Intelgic adapts the mechanical and sensor setup based on your process.

Q08Does the system provide Pass/Fail decisions?

Yes. You can configure threshold values for each product model or recipe.

If smoothness exceeds the allowed limit, the system immediately classifies the part as Fail/Reject and highlights the problem zone.
