SKU: SINE LSM-1-TM-G Category:


The Sinusoidal Visual Demonstration Array is designed to demonstrate the Modulation Transfer Function (MTF) of the human eye. Its transmittance varies sinusoidally and increases in spatial frequency from 0.2 to 20 c/mm, following a logrithmic scale. The modulation increases linearly from top to bottom. One can see, in the image, where the visual contrast contour disappears which is the MTF of the eye. Ideally suited for teaching and demonstration.

The SINE Sinusoidal Visual Demonstration Array is now available on either:
