1. Which component converts incoming light into an electrical signal in
a machine-vision system?
A. Lens
B. Image sensor
C. Trigger
D. Encoder
Answer: B
Rationale: The image sensor converts photons into electrical signals
that can be processed into an image.
2. What is the primary purpose of a machine-vision lens?
A. Store images
B. Illuminate the target
C. Focus and project the scene onto the sensor
D. Process image data
Answer: C
Rationale: The lens collects and focuses light so that the scene is
accurately projected onto the camera sensor.
3. Which lighting characteristic is most important when trying to
produce repeatable inspection results?
A. Decorative appearance
,B. Consistency
C. Maximum color variety
D. Random positioning
Answer: B
Rationale: Consistent illumination minimizes image variation unrelated
to the feature being inspected.
4. A camera's resolution primarily describes its ability to:
A. Change lighting color
B. Distinguish spatial detail
C. Increase conveyor speed
D. Control the PLC
Answer: B
Rationale: Resolution determines how finely spatial details can be
represented.
5. What is the main function of a trigger in a machine-vision
application?
A. Adjust lens focus automatically
B. Initiate image acquisition at a defined time
C. Increase sensor size
D. Replace lighting
Answer: B
Rationale: A trigger synchronizes image capture with the position or
movement of the inspected object.
6. Which factor most directly affects the amount of light reaching a
camera sensor through a lens?
A. Aperture
B. Ethernet cable length
,C. PLC scan rate
D. Encoder resolution
Answer: A
Rationale: The aperture controls the opening through which light enters
the lens.
7. What does depth of field describe?
A. Sensor data-transfer speed
B. The range of object distances that appear acceptably sharp
C. Number of pixels in an image
D. Lighting intensity
Answer: B
Rationale: Depth of field is the range around the focus distance where
objects remain acceptably sharp.
8. Which lens parameter is commonly expressed in millimeters?
A. Exposure time
B. Focal length
C. Pixel depth
D. Frame rate
Answer: B
Rationale: Focal length is a lens characteristic normally specified in
millimeters.
9. What is the purpose of image thresholding?
A. Convert image information into classified regions based on intensity
B. Increase cable bandwidth
C. Change camera mounting position
D. Synchronize a conveyor
Answer: A
, Rationale: Thresholding separates pixels according to whether their
intensity is above or below a selected threshold.
10. In a binary image, pixels generally have how many intensity
states?
A. Two
B. Eight
C. 128
D. 256
Answer: A
Rationale: A binary image normally represents two states, commonly
foreground and background.
11. Which lighting arrangement is often useful for detecting surface
defects through reflected light?
A. Structured or directional lighting
B. No illumination
C. Random lighting
D. Screen brightness
Answer: A
Rationale: Controlled directional lighting can emphasize scratches,
dents, texture, and other surface variations.
12. What is backlighting particularly useful for?
A. Measuring object silhouettes
B. Increasing network speed
C. Reading PLC memory
D. Eliminating all shadows from reflective surfaces
Answer: A
