Handmade Infrared Rays Complementary Metal Oxide Semiconductor (IR-CMOS) Camera for Recording Eye Movements

Abstract

Objective: It is important to observe eye movements in order to evaluate peripheral or central vestibular disorders in dizzy patients. An infrared rays charge coupling device (IR-CCD) camera is now widely used in daily practice. The technical advantage of a complementary metal oxide semiconductor (CMOS) now allows us to develop an inexpensive handmade camera for carrying out nystagmus recordings. Methods: We developed a handmade IR-CMOS camera at a reasonable cost of less than $150. The costs of a small IR-CMOS camera, scuba diving goggles, an AC adapter, an audiovisual (AV) cord, and a plastic board with a thickness of 0.
