Definitions
- the present invention relates generally to automation and computer engineering and it can be used as indicator for detection of optoelectronic objects when ingressing within a visibility thereof.
- TV camera by additional incorporation to the device for detection of the optoelectronic objects of electrooptical transducer (EOT) 3, the first input of which is optically connected with the objective outlet 2, its outlet is connected with the first input of photoreceiving * unit (PRU) with objective 4, picture monitor (PM) 5, the input of which is connected with the PRU outlet 4, videosignal processing unit (VPU) 6, the first input of which is also connected with the PRU outlet 4, synchronizer 10, the first input of which is connected with the outlet PRU 4 and its second outlet is connected with the second input of VPU 6, the 1st and the 2nd high voltage impulse sources 8, 9, their inputs are connected with the first outlet of the synchronizer 10, and the outlet of the 1st impulse source is connected with the third input of EOT 3, block of lock impulses (BLI) 7, the first input of which is connected with the outlet of the 2nd impulse source 9, its second input is connected with the third outlet of synchronizer 10, and its outlet is connected with the second input of EOT 3, remote control 14, the outlet of which is
- FIGURE 1 shows a preferred embodiment in accordance with the present invention.
- the present invention comprises an object for detection (1), objective (2), electrooptical transducer EOT (3), photoreceiving unit PRU with objective (4), picture monitor PM (5), videosignal processing unit VPU (6), block of lock impulses BLI (7), high voltage impulse sources (8, 9), synchronizer (10), frequency impulse laser (11), modulator (12), frame frequency divider (13), remote control (14), AGC (automatic grain control) scheme (15).
- the present device operates as follows.
- FIGURE 1 shows structure scheme of the device.
- the determined space volume where an object for detection takes place (1) is illuminated by laser impulse radiation (11) with repetition frequency f
- the laser radiation (11), reflected from object (1) and other object in the determined volume is received by the input objective (2), which forms the image of projection of the determined space volume on the input photocathode of EOT (3).
- the image signals, amplified by EOT (3), are projected at the photosensitive element of photoreceiving unit 4.
- the videosignals of the PRU 4 output are receiving by picture monitor (5), videosignal processing unit (6), synchronizer (10) and AGS scheme (15).
- Synchronizer (10) provides sychronous operation of high voltage impulse sources (8, 9), forming of the synchropulses, which control modulator (12) and accordingly laser (11), and also forming of sychropulses controlling block of lock impulses (7).
- the reflected on the electrooptical transducer signal is amplified only within the time interval, characterized by the duration of lock impulses ⁇ 3 , that is in accordance with the depth of instantly viewed space
- the change of the delay of lock impulses relatively laser radiation impulses determines the distance where the signals, reflected from objects, are received. Changing mutual position of lock impulses and laser radiation impulses from remote control (14), the subsequent view of the determined space of ⁇ R discrete depth can be provided.
- the indication of useful signal is its frequency f f /m cophased with the videosignal frame frequency. Due to these indications, operator emphasizes the signals of the optical devices (checking amplitude and repetition frequency) at the picture monitor (5); videosignal autoprocessing unit (6) will form the alarm signal owing to these signs.
- the AGS scheme provides supporting of optimal signal level at the input of photoreceiving unit (4) upon change of the signal level at the input objective pupil (2).
