DOE
Light Source:
• Type (cw laser, pulsed laser, LED, other)
• Wavelength (center and bandwidth)
• Polarization
• Power/Energy (average and/or peak)
• Beam profile (diameter, divergence, M² quality)
Optical Function:
• Desired light field distribution (shape, uniformity)
• Working distance
• Field of view / Diffraction angles
• Target surface inclination and/or shape
Application:
• Eye Safety requirements
• Element form factor (size, shape)
• Element material
• Environmental conditions
• Packaging of elements
• Sensor and/or screen type for light field (CCD/CMOS/ human eye/…)
Last but not least, the target annual production and a price target are required to choose the best solution.
Laser keyboard by a DOE
We tested our designed and fabricated laser keyboard DOE on 31 July 2012. The following picture shows the image of the actual laser keyboard, which was taken with a point-and shoot camera in natural light. Click the picture to see a larger image.
