The

thermal

radiation

of

the

observed

scene

is

focused

by

lens

(1)

to

the

matrix

of

hybrid

microcircuit

(4),

established

in

the

vacuum

cryostat

(5).

The

level

of

background

gating

is

limited

by

cold

diaphragm

(3).

All

constant

and

surge

voltages

necessary

for

the

work

of

photoreceiver

device

are

assigned

by

generator

(6).

The

device

of

calibration

consists

of

two

mobile

shutters

(specular

and

black),

controlled

by

electromagnets.

Electromagnets

are

governed

by

the

block

(9),

which

also

transfers

into

the

block

(14)

the

pulses,

which

synchronize

the

work

of

ATsP

(10),

adder

(11),

USB

connection

unit

via

USB

port

(15)

and

block

of

the

transmission

of

information

about

the

state

of

automate

(8).

Signal

from

the

matrix

photoreceiver

device

will

be

given

to

the

entrance

of

amplifier

(7).

The

amplified

useful

signal

is

transferred

to

the

personal

computer

after

processing

in

the

controller

(10

16).

On

the

housing

of

infrared

camera

there

are:

the

ring

of

image

focusing,

USB

2.0

port

for

the

connection

to

the

computer,

connector

for

synchronization

(7

‐

pin

connector)

and

fastening

for

the

installation

of

camera

to

the

stand.

The

indicator

of

the

readiness

of

instrument

for

the

work

is

installed

near

the

neck

of

cryostat.
