In a rolling shutter camera:

• The entire sensor is exposed simultaneously.

• Each row (or line) of the sensor is exposed sequentially in time.

• The shutter physically rolls in front of the sensor to control exposure.

• Only half the sensor is ever exposed to light at any given moment.

Which statement best describes a telecentric lens in machine vision?

• A lens that uses an adjustable zoom to maintain constant field of view.

• A lens that ensures magnification remains constant regardless of object distance (within its telecentric range).

• A lens that splits the image into two perpendicular views of the same object.

• A  lens that blocks any light not traveling along the optical axis.

How does an event camera primarily differ from a standard frame-based camera?

• It captures full-resolution frames at a fixed rate of 240 frames per second.

• It detects changes in brightness at each pixel and outputs asynchronous “events” instead of full frames.

•  It produces only a binary (black/white) image without grayscale levels.

• It requires an external trigger to capture each image frame.

Which of the following pairs correctly lists two common optical aberrations?

• Blooming and Rolling Shutter

• Chromatic Aberration and Barrel Distortion

• Microlensing and Specular Reflection

• Thread Inspection Error and Vignetting

Which lighting geometry typically highlights surface scratches or edges by grazing the object surface at a shallow angle?

•  Bright-Field (Front) Lighting

• Dark-Field (Low-Angle) Lighting

• Backlighting

• Dome (Diffuse) Lighting

When selecting a lens for a machine vision application, which of the following factors is typically the most critical to ensure you capture your target area at the required resolution?

•  The lens mount standard (e.g., C-mount, CS-mount)

• The lens’s focal length and sensor-size compatibility

•  The lens manufacturer’s brand reputation

• The presence of an integrated infrared (IR) cut filter

What is the primary advantage of using a lens with a larger aperture in machine vision applications?

• It allows for faster shutter speeds and better low-light performance.

• It reduces the overall weight of the camera system.

• It minimizes lens distortion effects.

• It increases the depth of field significantly.

Which type of lighting is most effective for enhancing contrast in images of transparent objects?

• Dark-Field (Low-Angle) Lighting

• Bright-Field (Front) Lighting

• Backlighting

• Structured Light Illumination

In machine vision, what is the purpose of using a high dynamic range (HDR) imaging technique?

• To enhance the visibility of details in both bright and dark areas of the scene.

• To eliminate the need for post-processing adjustments.

• To capture images at a lower resolution for faster processing.

• To reduce the amount of data storage required for images.
