Gross overexposure of the IR results in:

• A. Saturation
• B. Oversampling
• C. Extreme latitude
• D. High spatial resolution

Answer: (A)

When the image receptor is grossly overexposed, it’s pushed beyond its usable range and the signal hits the maximum the detector can record. This is saturation: the brightest areas become completely white because the pixels can’t differentiate higher intensities any further. As a result, you lose detail in those overexposed regions and the overall image contrast is compressed.

Oversampling isn’t about exposure levels; it refers to how data are sampled, not how much radiation reaches the receptor. Extreme latitude describes a receptor’s ability to handle a wide range of exposures without losing information, which isn’t the specific outcome of gross overexposure. High spatial resolution is about distinguishing small details, not about how much exposure the IR receives.
