OPTICAL ILLUMINATION DEVICE
An optical illumination device (10) includes: a laser light source (1); microlens arrays (2, 3) through which light emitted from the laser light source (1) passes; a moving mechanism (5) that moves the microlens arrays (2, 3) without changing an optical length from the laser light source (1); and a...

| Zusammenfassung: | An optical illumination device (10) includes: a laser light source (1); microlens arrays (2, 3) through which light emitted from the laser light source (1) passes; a moving mechanism (5) that moves the microlens arrays (2, 3) without changing an optical length from the laser light source (1); and a Fourier lens (4) through which light passing through the microlens arrays (2, 3) passes. |
