  • Optical displacement sensor and method for sensing linear displacements in a shock absorber
    Patent number: 5371598
    Abstract: A device and method for sensing linear displacements between a first member (101) and a second member (102) on a same axis (108). The second member (102) substantially encompasses the first member (101). To sense the linear displacements, an optical code pattern (103) is placed on the first member (101) and an encircling optical sensor (104) is placed on the second member (102). The encircling optical sensor (104) includes light transmitting (106) and receiving (107) paths that transmit and receive light to/from the optical code pattern (103). The light received from the optical code pattern (103) is sent to a displacement calculation device (105) that determines the linear displacement of the first member (101) with respect to the second member (102).
