Now to the further quantitative description of Fig. 3 a events.For description colour gamut size, we must obtain the chromatic stimulus value of light source, such as：
Wherein I () is light source light spectrum distribution.It is standard stimulus curve.In xy color spaces, chromaticity coordinates is：
The blunt xy coordinates according to RGB light source of z=l-x-y, can calculate the size of colour triangle.For quantitative description speckle, it is irradiated to provided with light intensity is hooked on screen, due to the property of phase thousand of laser, the luminous intensity of screen reflection or projection produces inhomogeneities（That is speckle）, picture light distribution is (p is the probability of intensity I）, then the definition of speckle contrast is：
Wherein, 7 be light intensity average value to I, is standard deviation.Can be by calculating both this.The ρ (/) of actual projection system screen is strictly calculated, it is theoretical extremely complex.Stress light source discussion now.To conventional Solid State Laser, its spectrum is very narrow, can be approximately perfectly correlated light, and its Speckle Intensity Probability Distribution is negative exponential function： (/) = =exp(-//7)
Can be approximately complete irrelevant light due to the non-constant width of spectrum, its Speckle Intensity Probability Distribution is function to fluorescence light source：
Ρ2(Ι)=δ (Ι) is just blunt according to distribution function pi, p2 and LASER Light Source and fluorescence light source mixed proportion, and we can obtain the intensity distribution function of synthesized source, and then obtain speckle contrast.Fig. 3 b are the result of calculation of Fig. 3 a examples.Here blue light uses laser LD, and feux rouges uses LED, and the chromaticity coordinates point of blue light and feux rouges is another1J is（ 0. 1813 , 0.0818 ), ( 0.6190 , 0.3521 ).Green glow uses the mixing of Solid State Laser and fluorescence.The centre wavelength of Solid State Laser is 532nm, with a width of 0.1nm.Fluorescence centre wavelength is 532nm, with a width of 80nm.Fig. 3 b are the change of corresponding colour gamut and speckle contrast change when green laser fluorescence is than changing.Curve A represents speckle contrast in figure, we can observe that when fluorescent component increases to about 60% from 0, speckle contrast Jiang Shi is not obvious in the decline of 60 90% contrasts, crossed 90% right continuation and has declined.Such change behavior be by quantum condition entropy and distribution synthesize caused by.Curve B is the relative area of colour triangle（Colour triangle area ratio when i.e. colour triangle area is with pure green-emitting fluorescent）, it may be seen that when fluorescent component increases, colour gamut diminishes.To reduce the purpose of speckle contrast and the design of increase colour gamut, about 60% fluorescent component is maximally efficient.At this moment speckle contrast is reduced to 27% by the 100% of pure LASER Light Source, while xy space gamuts area adds 32% than pure fluorescence light source.It is pointed out that to calculate simple reason, gamut area is carried out in xy color gamut spaces, because the heterogeneity in xy spaces can underestimate colour gamut increase, actual colour gamut face increase can be higher.The colour gamut of fluorescence light source is too small, and color saturation is low, is only suitable for some commercial projection applications, by the mixing of laser and fluorescence, the colour gamut after increase can meet the demand of the entertainment applications such as home theater.In addition, speckle contrast about small must be just not aware of to 5% human eye.The complete phase thousand of light source, in systems in practice due to the use of laser array, various random devices and process in system are assumed in this instance, even if not mixing fluorescence, laser has not been the complete light of phase thousand, and speckle contrast is not 100%, it is different according to optical system, small it can arrive 15-20%.Mixed by the laser and fluorescence of the present invention, be that speckle contrast can be reduced to 5% degree.Fig. 4 is that the use blue laser for occupying the embodiment of the present invention is used as the wavelength schematic diagram of excitation light.When using blue laser as excitation light, can design the mode of fluorescent excitation only makes some blue light be converted to green glow.So remaining blue light can be used as blue light source.
