Patent ID: 10976553

Abstract:
It is an object of the present invention to provide an optical scanning apparatus and a retinal scanning head-mounted display that prevent an overcurrent from being supplied to a light source.An optical scanning apparatus of the present invention includes a light source (125) configured to emit light; a light source driving unit (124) configured to supply a driving current to the light source; an optical scanning unit (30) configured to scan the light emitted from the light source in accordance with an image signal such that the light is projected onto a projection surface; a light amount sensor configured to detect an amount of the light; a current sensor (140) configured to detect the driving current; a primary stop control unit (122) configured to stop an operation of the light source driving unit when the amount of the light is equal to or exceeds a predetermined amount of light; and a secondary stop control unit (150) configured to stop supply of the driving current to the light source when a value of the driving current is equal to or exceeds a predetermined threshold.
