The slotted optical switch, sometimes known as opto switch or optical switch but not to be confused with the optical component, is a device comprising a photoemitter (e.g. LED) and a photodetector (e.g. photodiode) mounted in a single package so that the photoemitter normally illuminates the photodetector, but an opaque object can be inserted in a slot between them so as to break the beam.
Optical switch technology was introduced in 1962 by Harley E. Kelchner for use in a typewriter machine with the purpose of reducing the noise generated by typewriter keys. An optical keyboard technology utilizes light-emitting devices and photo sensors to optically detect actuated keys.
Combines optical sensor with an accelerometer, allowing the mouse to track speeds in excess of 500 inches per second, and more than 16G in acceleration. 108 g (3.8 oz) (without cable) 144 g (5.1 oz) (with cable)
An early Xerox optical mouse chip, before the development of the inverted packaging design of Williams and Cherry. The first two optical mice, first demonstrated by two independent inventors in December 1980, had different basic designs: [1] [2] [3] One of these, invented by Steve Kirsch of MIT and Mouse Systems Corporation, [4] [5] used an infrared LED and a four-quadrant infrared sensor to ...
