Abstract

The resolving power characteristics of three contemporary high-speed imaging systems were evaluated under nearly identical test conditions. In generic terms, the image-recording sensors evaluated in this study consisted of 1) a high-speed 16mm color film, 2) a high-speed monochrome and color video, and 3) a monochrome solid-state CCD sensor. The commercially available cameras embodying these sensors were 1) the Locam 16mm high-speed intermittent camera, 2) the NAC HSV-200 high-speed video camera, and 3) the Spin Physics SP-2000 and Ektapro 1000 cameras. Resolving powers at three target contrast levels were determined using the same objective lens on each camera system with the same aperture setting. Spatial resolutions for all three systems are expressed in terms of total information bits per frame. This resolution metric for 16mm color film exceeds those of the other image sensors by a factor of 2:1 for low-contrast subjects and over 5:1 for high-contrast subjects.
