 laser pointer can meet the needs of the customer.
Mainly by high-speed comparator and its subsidiary circuit. Input Gaussian pulse signal is divided into two: all the way through the delay circuit delay added to the high-speed comparator inverting input and the other path attenuation circuit added to high-speed comparator inverting input of the comparator transitions occur in the two input moment of the relative size of the end of the signal change, the role of the threshold amplitude greater than the specified threshold signal to produce a corresponding output signal at the output, which prevents noise and false triggering, reducing the false alarm rate of the system. Delayed attenuation circuit design: the signal after a certain device and transmission line there is always a slight time delay, the delay of high-speed analog signal is generally achieved through a transmission line. Lead the healthy consumption of laser pointer industry.
Design considerations to achieve the delay of the signal RC delay circuit consisting of capacitance and resistance. Specific circuit is as follows: the structure and principle of laser camera. The basic structure. Laser printing systems: including laser transmitters, regulators, divergent lens, polygonal lens, focusing lens, high-precision motors and rollers. Film delivery system: send the cassette to close the cassette, sucker, rollers, motor and power transmission components. Its function enough to remove the film from the sheet feeding box after transmission device to send a laser scanning position, when the film exposure is completed and then transfer it to the closing piece box or directly to the washing machine lose Piankou, to complete the film conveying task. Information transmission and storage systems.This advantage of laser pointer can attract more and more customer
Abstract: This paper KODAK 8100 camera a few failure analysis, check the possible ways to solve the fault and prevent failures from happening again, for the peer reference. KODAK 8100 laser camera, a Kodak Company introduced a few years ago, print and slice one dry-type semiconductor laser camera design, low failure rate, the more ownership. In this paper, several fault common to talk about their own maintenance experience, or to give peer reference. Failure: Boot error in the heating drum preheat the P551 (not warm-up imaging device, the imager can not be printed). Analysis of maintenance: failure prompted the instrument self-test after the preheating process.Dry laser imaging using a laser beam scanning of film exposure to generate the latent image, laser imager, laser point in the X and Y directions form a clean, sharp edges, thus providing higher resolution, print resolution from 325 dpi to 650dpi, 14 16384 gray.
