Abstract:
PROBLEM TO BE SOLVED: To reduce transmission loss during the transmission of an optical signal in a method for controlling a gap width in an optical element. SOLUTION: A method for forming a gap includes a step for forming sidewalls 18, 20 in a microstructure and a step for determining a width d of a gap 16 between the sidewalls 18, 20. The gap 16 has a width d defined between the sidewalls 18, 20. Where the determined width d of the gap 16 is below the selected tolerance limits for the width d of the gap 16, at least one of the sidewalls 18, 20 is consumed to form a gap which meets the selected tolerance limits.

PROBLEM TO BE SOLVED: To solve the problem that the saturation of either one of colors is limited by using a color wheel in an LCD projector. SOLUTION: A projection system includes a display apparatus comprising a plurality of tunable Fabry-Perot filters, each of the filters being configured for shifting between a state in which the filter transmits radiation in a bandwidth in the visible range of the electromagnetic spectrum and a state in which the filter transmits radiation in a bandwidth outside the visible range of the electromagnetic spectrum. An illuminator provides light to the plurality of Fabry-Perot filters. A control system receives image data and controls the display apparatus to project an image onto an associated display surface. The control system includes a modulator which provides wavelength modulation signals to the plurality of Fabry-Perot filters to modulate a color of pixels in the image and causes selected ones of the Fabry-Perot filters to shift into the bandwidth outside the visible range to modulate the brightness of pixels in the image.
