摘要 |
<p>A light source unit (110) emits linearly polarized laser light of a given wavelength. A wave plate (121) transmits the laser light emitted from the light source unit (110) and has a phase delay axis of which the direction is adjusted to about 0 degrees with respect to the polarization direction (101) of the laser light. A liquid crystal cell (123) transmits laser light that has passed through the wave plate (121) and by a switchable rotation amount, rotates the polarization direction (101) of the laser light transmitted through the liquid crystal cell (123). A wave plate (125) transmits laser light that has passed through the liquid crystal cell (123); and further has a phase delay axis of which the direction is adjusted to about 0 degrees with respect to the polarization direction (101) of the laser light.</p> |
