Hikrobot MV-CL line scan cameras
Line scan cameras for continuous inspection
An MV-CL line scan camera captures one narrow image line at a time while the material moves. Successive lines form a continuous image of film, paper, foil, coils, glass or long profiles.
Line format
4K, 8K and 16K classes
Image output
Mono or color
Interfaces
GigE to CoaXPress
Resolution across the material and sampling in the direction of movement are determined separately.
Image geometry and production speed
What determines line format and line rate
Material width and the smallest relevant feature determine the pixels required across the web. Transport speed and the required sampling in the direction of movement determine the line rate.
Sizing relationships
Across the web: field width ÷ pixels per line = object-space sampling.
Along the web: transport speed ÷ line rate = distance per line.
When the complete relevant surface fits within one field of view, an area-scan camera is usually the simpler option.
01 · Geometry
Width and smallest feature
The material width and required object-space sampling determine the corresponding line format.
02 · Motion
Speed and encoder
An encoder can trigger each line from material displacement when speed varies or slip affects image geometry.
03 · Exposure
Line light and contrast
The exposure must fit within the line period, while the line light must provide enough contrast at production speed.
04 · Data path
Interface and processing
Line format, line rate and bit depth determine the data stream that the interface and vision PC must process.
34 active configurations
The Hikrobot MV-CL line scan family
MV-CL includes documented 4K, 8K and 16K configurations for monochrome or colour acquisition, with interfaces from GigE to CoaXPress. The suitable combination follows from the required line format, line rate and data path.
Line rate, pixel size, lens mount and interface availability vary by SKU. Selected documented models reach up to 80 kHz; the available operating modes therefore need to be checked for the chosen configuration.
Line format
The required pixels across the field width follow from the smallest relevant feature.
Mono or color
Monochrome models suit intensity-based inspection and higher sensitivity. Colour models are relevant when colour differences contain inspection information.
Interface
Throughput, cable architecture and host hardware determine the suitable interface. Optics and lighting remain separate choices within the imaging setup.
Where line scan fits
Continuous material and long surfaces
Line scan suits products whose inspection length does not form a practical frame boundary. The camera captures one line while controlled movement supplies the second image dimension.
Film, foil and paper
Continuous webs can be inspected for surface, edge and print-related defects.
Print and labels
A continuous image supports registration, print-quality and missing-content checks.
Coils and long profiles
Line scan maintains consistent sampling for products that extend beyond one conventional field of view.
Glass and flat material
Stable transport and line lighting provide uniform coverage of glass and other flat materials.
A complete line-scan system
Motion
Encoder quality, transport stability and slip affect image geometry.
Optics
The lens must cover the long sensor with sufficient resolution and focus.
Lighting
Focused line lighting must provide contrast within the available exposure time.
Processing
Interface, host memory and algorithms must keep pace with the data stream.
Technical background
Compare the imaging methods
The technical guides explain how line images are formed and how line scan compares with area scan when both methods are possible.

Discuss your line scan application with a specialist
Material width, smallest relevant feature, transport speed, surface properties and installation space determine the required line format, line rate and data throughput. Sedeco can use these values to compare the camera, optics, lighting and processing options.

The field the sensor must cover.
Smallest relevant feature
The defect or edge that must remain measurable.
Transport speed
Minimum, nominal and maximum speed.
