Title:
密閉筐体を有する相対運動センサ
Document Type and Number:
Japanese Patent JP2008524690
Kind Code:
A
Abstract:
An optical input device (110), such as a computer mouse or the like, in which the so-called self-mixing effect in a diode laser is used to measure relative movement of the device (110) relative to a surface (120). A housing (112) contains an optical measuring module (114) comprising a laser (3) and detector (4). The housing (112) fully encloses the optical measuring module (114) and comprises a base plate (116) having a transparent window (124) through which the surface (120) is illuminated by the measuring beam (13) and radiation reflected by the surface (120) can return to the laser cavity. Because the housing (112) is fully enclosed, no ESD shielding is required and the device can be made liquid-tight.
