Description
Technical field
The present invention relates to the technical fields of imaging system, more particularly to a kind of lens scan imaging system.
Background technique
It is well known that modern projection technology, is mostly that high power light source shines, then by control 3LCD or DMD, uses phase
The optical lens answered, projects on screen;
Modern projection technical disadvantages: in existing 3LCD shadow casting technique, because of the low (liquid crystal of early stage of the light percent of pass of LCD
Shield light transmittance also below 10%, so brightness is darker, angle position is unintelligible, while light source such as 500W or 300W that will be very big
Light bulb just can be used.Select from the secret in " computer weekly " 47 phase LCD in 1999 and DLP projector, domestic number of the edition: CN 31-
1427/TP), light source utilization rate is with regard to low, so projection device is had to using high power light source, it is big that light source consumes power.It is common
Metal halogen light bulb and high-pressure mercury bulb (UDP and UHE), consumption 100 watts to 250 watts of power (UDP have 100W, 120W, 150W,
Several grades of power requirements of 200W, 250W.It selects from 33-35 pages of the phase of " China Electronics's market conditions: audiovisual front " 2010 the 1st.Country's periodical
Number: CN11-3648/F) service life, short (metal halogen light bulb generally will reduce by one using 1000 hours or so original brightness
Partly ... UDP's lasts a long time, and is generally nominally 6000 hours ... because of calorific value height, wants to heat radiation system of projector
It asks also high, should not continuously use for a long time.It selects from 33-35 pages of the phase of " China Electronics's market conditions: audiovisual front " 2010 the 1st, it is domestic
Number of the edition: CN11-3648/F).Technically, long-life light source can not be also manufactured at present, and brightness is not high after projection, image quality
Generally.In existing DLP shadow casting technique, for DMD as light reflector part, it is only slightly larger than 60% light utilization efficiency, and
Dmd chip is easily damaged.Image quality is projected not as good as LCD, it is also difficult to accomplish high brightness and high-resolution combination.Likewise,
The power consumption of light source is big, and the service life is short.This makes projection device working service at high cost.
Because projection device core component (LCD, DMD) manufacturing technology limits, projection device image quality is not as good as colour TV and shows
Show device.Currently, the defect of 3LCD projection and DLP projection, is unable to satisfy demand of the people to large screen high brightness high definition device.
Now, laser and LED light source are as light source in projector with (Sony Corporation of Japan successfully develops one
The laser light source module of high efficiency rgb color mode of the money towards large screen projection equipment.Select from " dual-use technology and production
Product " 2010 years 4 monthly magazines page 30, domestic number of the edition C N:11-4538/V).Laser have brightness height, good directionality, monochromaticjty it is good,
Coherence is good.Therefore, laser scatters less (decaying is few) in air, can project on extra large screen at a distance.Red,
Green, Lan Sanse laser is on the screen after colour mixture, and bright in luster, better than the picture quality that other light source projects are formed, brightness is high.It is
Preferred light source.Although the light quality that LED light source generates is good without laser, its cost is low, has advantage in specific occasion.
